We just did a 2 week round trip from San Diego to Wisconsin and back, appx.
5,000 miles. We were towing the wife's Taco on the car trailer and I was
surprised that we got about 8.1 mpg, especially with all the mountain grades
and running about 70 mph most of the time. Here's the tow rig.

It al depends on how heavy my right foot is and where I'm driving.

Since im always gettin it and live at 4000' on a winding road I get average 15-16.

I think that's great mpg for how and where I drive.

I can squeeze 18-19 if I go super easy on it and keep the engine below 2K

On my way back from Texas when it was stock it was around 20.5mpg but that went to shit when driving through NM and AZ where the 18 wheelers drive 80mph.

In order to get good mpg you need to baby the shit out of your truck and keep it at 65mpg.

07 CTD 6.7 / 6sp manual / 3.73

65-70 mph
Terrain is constant rolling hills

2006 Dodge 2500 QC 4x4 CTD with 26K miles. No mods other than an Airraid drop in filter. I average 15 - 16 mpg towing at 70-75 mph....Jeep and trailer weigh around 7K. I have found that I get my best mileage by keeping the truck under 2000rpm, whether I am towing or just driving.

Towing my Jeep, I get anywhere from 13-15 mpg depending on hills and how bad I want to get where I am going. I notice the best mileage around 65-58 mph, also under 2000 rpm.

02 cummins auto, 4" exhaust, air intake and an Edge chip. Otherwise stock.

I get around 11- 12 mpg from LA to the Rubicon towing the Jeep with our Yukon. 5.3L with 4L60E trans.

I am currently getting between 3 and 7 mpg in the RV, but it is hard to tell we have been running the generator like crazy during the summer. At some point I need to just drive it somewhere to check for the mileage without generator useage. 32ft Jayco, 8.1L Allison. RV weight is ~17,000lbs.

you went to WI and didn't stop by to say hi? Bastard. :flipoff2:

I get 10-11 in my Tundra towing the 4Runner and a weekends worth of camping gear.

9.8 mpg towing with the 'burb.

not much better not towing. They just seem to get shitty mileage no matter what:laughing:

About 19-21 in my 04' CTD...I found my Quadzilla on the 60hp setting gives me 2-3 better mpg (if I can keep my foot out of it).

That's hand-calc'd mpg btw...

My last round trip from OH to FL and back I averaged 11.8 mpg over 1600 miles. Empty 18ft car trailer going down. Towing a stock '99 GMC Sonoma home. Speed was 7 mph over speed limit at all times. So mostly around 77 mph from TN on.

2001 Dodge Ram 2500 4x4 SRW, Quad Cab, Long bed, 3.54 gears, automatic, V10, 33" tires.

last trip was recent, Chicago to Hot Springs AR (Superlift park) and back.

we typically got 11mpg running 75-80mph with the AC fullblast (AR was 106 every day!!)

'02 d-max with EFI, exhaust and 33s. not too bad :grinpimp: (rig and trailer should be around 7500#)

sorry for the dark pic, the sun was setting. my cuz taking a break since he was hobbled and still a trooper for some wheelin!

http://i7.photobucket.com/albums/y280/1TFROT/superlift%20park%2007/Picture021.jpg

Haulin 2 rigs on the trailer with all gear (whole setup roughly 24K) I pull 11mpg at 75mph. My rig is modded as listed in my sig. If I slow it down to 55mph I have pulled 13.5mph. I towed a single place trailer with my rig on it (whole setup roughly 13k) and pulled 14mpg on the way to moab this year. I did do roughly 7 - 10 over the posted speed limit but I was suprised that it wasnt better. It seemed odd that if I pull twice the weight I only drop 3 more miles to the gallon. Less than that if I slow it down.

SanDiegoCJ, Id say your doing pretty good at 8.1mpg in that rig.

Mods that used to be in my sig

99 24valve CTD 5 spd 4x4 Dually 3.55 gears. F.A.S.S. Smarty , jammer 3, Isspro gauges, BHAF, ATS Exhaust manifold, and straight piped.

Mine was around 11-12 round trip from Sacramento to Coos Bay, OR. Im guessing I was weighing in around 18-20K

This load netted me 11-12 mpg doing about 75mph.

http://i69.photobucket.com/albums/i49/KrisKelso/DSC05273.jpg

This load drops me down to about 9-10 mpg, normal hwy speeds.

7.5 most of the time, and a touch over 8mpg if I watch the vacuum gauge while I'm driving.

'74 IH 1T 4dr long-box, with a hopped up 392 gasser, pulling a 16' trailer with a rig on it.. 12,500lbs at the lightest, ~16k at other times.

Gary, with mine full load at 56MPH, 10 MPG. 66-70MPH, 8.3MPG or so.

Last time I towed the Jeep... I got around 14-15mpg. I don't remember the exact figure, other than it was around there. Unloaded I get 16-17mpg.

Jeep/Trailer is just a bit under 8000lbs. Truck, trailer/Jeep and all the gear is roughly 16,000lbs.

Oh, truck is a 98 24v 2500 Ram on 35s


I'm curious to see what my brother's truck does towing the 73 "1 ton" Early Bronco he's building. It's a 07 Chev 2500HD with the 6.0. He's been getting 14mpg unloaded... I guess that's not too bad for a gasser.

99 F-350 Crew LWB: 160k on 7.3l 6-speed
18' trailer

towing Jeep (LJ) on 36's from Denver (5280') to Moab over 2 major mountain passes (10,000+) nets me around 11-12mpg. Regular highway speeds....65-75mph.

02 f250 4x4 crew cab longbed w/ a 18' trailer and a 5800lb jeep. total weight 16460lbs 12mpg going from 55 to 70mph.

5.6L Titan
10-12 mpg @ 70-75 mph, with a 7,000 pound load. It's alright for a gasser.

Our 454 got about 9-10 unloaded, 8-9 pulling a loaded car trailer, and about 5-7 pulling our 2000 gallon water trailer.

....but it is hard to tell we have been running the generator like crazy during the summer. At some point I need to just drive it somewhere to check for the mileage without generator useage. ...

As a general rule, generators will burn roughly 0.5 gallons for each hour....

IF you're running it on the road AND on a long trip.... It seems as if no matter how fast you drive, when you factor in stops, you end up averaging 60 MPH - at least it seems that way for me.

Using that 60 mph average, the 0.5 GPH translates into 120 MPG.

04.5 CTD 600 NV5600, long bed 4x4. Gets about 15mpg towing my 24' car trailer and jeep combo. It'll get a little worse when my 35" Pro Comp Extreme All Terrains get here though.

Speed limit or better the whole way, Denver to Calgary and back, about 3 000 miles. Best tank was 9 worse was 6 mpg. (8.1, 4l85E, 4.10s). Weighed in at 19 000 lb combined on the scales (10200 lb on trailer axles, 8800lb on Chevy). With the small trailer, which lowers the drag I can get 9-10mpg, weighing about 17 500lb - 18k.

That's pretty similar to my '99 crewcab PowerJoke w/auto. I can manipulate the mileage a little by staying at or below 2000 RPM.

I went this weekend, probably stayed around 65 most of the time ~2000 RPM I got 12 mpg pulling about 6K. Its pretty much within a gallon or two of that most times. I've gotten around 9 going to Nebraska, about 90 mph the whole way, and as much as 13 to Montrose or Moab going ~70-75.

Tow rig in sig.
Im not going to get into teh details of what leval was on what for the power controller. Just giv 2 scenerios.

went from Diomand springs to Torrance )la area) unloaded there and back with a load of 3k maybe. I got 18 on the nose averaged for round trip.

went to teh hammers and back from same area leaving. loaded both ways with gear and trailer and rig = 7k. i got 19+ give or take. I was way happy only stoppping twice to fill. once in barstow to be safe and once in elk grove on the return trip to also be safe as grant line rd offers nothing for fuel up in the hills.

i think the winner with my set up is at 65-70 pulling the cruiser and trailer @6k ish im turning 1800 rpms on flat. shift into 4th for the hills to pull the same speed @ 2400 ish rpms

anyhow. love my truck!!!!

07 Dmax brand new off the show room bought with around 100 miles on it and towed the boat with 1900 miles on it. This setup averaged only 9.2 mpg at 75mph! The Nautique only weighs about 5000lbs give or take depending on fuel and other gear.

towing in 4x4 across utah and wyoming in the snow going 45mph with the fuel turned down 3 years ago, i got 14mpg.

The truck doesnt have enough power with the tire/gear ratio IMO to tow any faster. It uses too much fuel trying to go 70 towing my trailer.

I am seriously considering finding some 3.55 gears and swapping them for my 4.10's and I think I will get 2-3 mpg better.


Buddy of mine had a '92 12-valve Cummins with 4.10's, a 5-speed, and 245/75's. He could tow up the steepest hill in 5th at 30 MPH & accelerate, but he started to overheat at 65 MPH even running empty. Too many RPM's. A swap to 33" tires helped him a BUNCH & didn't rob him of too much low-end power.

Now granted, you've got a newer truck & I don't know what your FINAL drive ratio is (the early 5-speeds didn't have much of an overdrive, not sure if the later ones do or not). So, dunno if this is the direction you want to go or not, but in theory it sounds reasonable.

I now have a SnugTop camper on it, but other than that, it's the same as the pic. I got just under 15mpg to Moab and back, but I was going slow, (a stock 12v CTD was slowing me down :laughing:). To the hammers and back I usually can get about the same. I usually slow down to 60 or so once we get into California, as we've been stopped and warned a couple times. Both of these drives get into the boost pretty good at one point or another. I don't know what I could get on flat ground, but I know it's way better than it was stock.

I bet the generator draws more than .5 gph if it's powering the A/c unit

Im also thinking that ultra low sulfer fuel isnt as good for mileage but it might be in my head.

I have the same truck and pull about the same load, 9mpg. Unloaded I can sometimes get 12mpg, but that's with a 50 mph tailwind (or voo-doo math).

I had a '99 GMC 454 Automatic Crew Cab Short Box 2500 4x4 with 285 BFG All Terrains and stock 3.73 gears.

I got exactly that mpg.....6-7 towing (usually closer to 6) and 8-9 empty. Best tank ever was 11.

my old topw rig is a 93 suburban 454tbi 4L80E 2wd silverado. on the highway it'd get as much as 17mpg empty and averaged about 10mpg towing 7000 pounds.

currently for sale if anybody wants a cheap tow rig!!!!! needs front brake work, besides that it's very clean and only 130k miles on it. $2500 firm.

I once achieved ~25 for a couple hours with the empty trailer at a snail slow, recordbreaking pace across Austria :D

Iveco 2.8 turbodaily, aerodynamics goes a long way :flipoff2:
http://toy4x4.free.fr/passiont/photos/misc/iveco_55.jpg

'03 Chevy 2500HD CC/SB, 6.0L gas, 4L80E, 4.10 gears.

Gets 14-16 mpg average to and from work (a decent amout of 65 mph freeway) while empty.

Pulling an 18' flatbed with a 1-ton full-bodied K5, 4" lift on 38's that weighs about 8,500 lbs. total, plus firewood and camping gear for a long weekend. Get about 9 mpg running relatively hard on a 50/50 mix of freeway and twisty back roads. Always running the speed limit or above.

The aerodynamics of the load is just about as important as the total weight...taller vehicle = significantly more drag.

Up and back to the con this past week, full bed, pregnant wife, daughter, dog, gear and 5300 in trailer weight I got an average of thirteen behind an 05' toyota tacoma with a v-6 at 70 mph.I was VERY surprised.

Towing just the Jeep, no camper I just got 15.6 from here to the Rubicon, Rubicon to Mariposa, and back. Usually around 13 with the camper on it. Both at around 70 mph and not really slowing down for the grades..

And it seemed to have decent power, too. (Except going up the 50, lol)

8.5mpg @ 75

I can get 9+ really trying @ 65 (18spd so 2 od gears) it drops to 6.5mpg at ~80k lbs. I'm 19k empty so up to like 45k it's 8.5mpg

99 Detroit 14L 575/1850 - 18spd - 3.55 rears

Normal towing my Jeep back east I was getting ~12mpg if I kept it under 70mph, but I have noticed a slight decrease since I've been loving over 5,000 feet. Last trip to Buena Vista I got about 11mpg, but I was floggin her up some of the mountains :D

When I moved from Virginia to Colorado I had everything I owned with me in the truck and on the trailer. I was doing the speed limit most of the time, which is 70mph most of the way. It was HOT (~100 the whole time) and I had the A/C cranked the entire trip. I averaged 10mpg. Weight was approximately:

- Truck: 7,250lb
- In the bed: ~2,500lb
- Trailer: ~7,000lb
- TOTAL: About 16,750lb

(Yes, I know I need airbags!!)

Just got back from a 280 mile round trip towing our camper and averaged 9.5 mpg hand calculated. This was a mix of 2 lane back roads, 2 lane highway and 4 lane interstate. Most of the time I was 7-8 mph over the speed limit. Truck is an '03 2500, hemi, auto, 4x4, and 3.73 gears. Camper's weight is a little over 5k estimated. It is a 2007 Jayco 232 EXP featherlight with a claimed dry weight of 4100#. It's definitely more about the wind resistance than the weight!

'87 27' Winobago with 454 and auto, no overdrive pulling the toy on a flat deck averaged about 7mpg from Texas to the hammers. Coming back with just the trailer no rig, we got 8-9. I am thinking of putting a 12V in it, so maybe I can get better milage, the gasser sucks in the hills.

'89 Chevy V3500 with a warmed over '91 454 and 4L80 with 4.56's and 37's and too much lift.

10-11 mpg unloaded on hwy
8-9 mpg unloaded city
5-10mpg towing depending on load, speed, wind and hills.
Averaged 8 or so going up to the 'con, speeds ranged from 55 to 85 depdending on traffic, GCW 12500 lbs.

'01 Durango R/T (5.9L, 3.92s, AWD) towing my old YJ on 35s with gear (4,000 ish) on my little 12' tandem axle. (I'd guess <12k total)

Loaded as above: 8.5 mpg, maybe 9.0 if I keep it below 75 mph.

Unloaded: 11 mpg around town, maybe 13 if I keep it below 75 mph.

I haven't towed the CJ yet since it won't fit on my trailer (full width & 39.5" swampers), but I'd guess 7.5 mpg towing that.

99 CTD 3500 2wd 5spd

Emtpy everyday driving with commute is 18.9mpg. Towing 11.5k was 11.3mpg over teh 1900 mile roundtrip. I was running 70-72 on the flats and keeping 50+ in the mountains.

2004 4x4 Tundra 12to13 mpg towing with 14 Ft Featherlite trailer and Jeep 327560

10(maybe) empty

1996 Dodge 2500 V10 4x4

Unless i missed it.......I didnt see anybody reply thats towing with the Triton 5.4 V8?? Or the 5.7 hemi ?? Im in the market for a tow rig and was looking for comparisons.....Thanx :flipoff2:

My Hemi got around 10 or 11 towing with the cruise set at 60. On hills I dropped it out of OD and slowed down to 55. It was painful.

86 F-250 with a 6.9L Diesel
Gets 15-18 mpg unloaded depending how I drive...
Loaded it gets around 10-12 just because i have to pour the fuel to it to stay moving.
I do believe it has 3.73 gears but I'm not 100% sure. I was rather surprised that it was getting those numbers.

Mine was around 11-12 round trip from Sacramento to Coos Bay, OR. Im guessing I was weighing in around 18-20K

i saw you out there....i live in reedsport...by coosbay...anyway i get 9 with my old ford F-250 460 EFI..2wd

01 5.4L 2v towing 4200lbs I averaged about 9.5mpg and finished the majority of a 22gal tank in 2 hours. Not great but it did alright.

Yep. Driving like an old ugly grandma.. :flipoff2:

I can get 14mpg when towing if I keep it around 65-70 mph towing 7K lbs.
2000 Cummins 4x4, 6 speed with some minor fueling mods. Towing 85 MPH gets me about 10mpg.

I got 11.5 with this set up doing 70+ MPH. On the return trip, I backed it down and kept it under 70 and got 12.9. I was pretty pleased. Towing just one rig gets me about 14 MPG.

04.5 Cummins with intake, exhaust mods and a Quad box. When towing I keep the box on the mildest tune.

Towing 85 MPH gets me about 10mpg.



towing at 85mph gets me tickets........

I pretty much get 12 across the board with any load I've hauled thus far. The buggy and small trailer (6500 combined), the Willys and small trailer (8500 comb, plus a weeks worth of Rubicon geat AND the kitchen sink), the Willys and the big trailer (10500+ comb), or the buggy and the big trailer (8500 comb). Empty I managed to squeek 13.9-14 out of it on a 400 mile round trip where I set the cruise at 65. I typically drive 75 unloaded and 70 loaded. 06 f350, CC,LB, 4x4, tow boss (4.38 ls)...


:usa:

this wind break dropped me down to 11.5 @ 70+ for 200 miles ;)

the bed is full of fire wood and a 4x4 quad. the wood was hand placed under and all around an packed as tight as we could get it all the way to the bed rails. the trailer was loaded with wood all the way up to the bottom of hte buggy and all the way hanging off the rear. I'm guestimating the total load at 14K and some minor wind resistance ;)

PS yes I managed to round up 7 x-mas trees in March for TDS :laughing:

F250 Stock 7.3 Auto with 35s and an air raid intake box and filter. 26,900 LBS, 35 ft 3 axle tag, 10,000 LBS weight distributing hitch cinched up a little to tight, running a fairly consist 72 MPH with the cruise and with the a/c on managed to get 14.5 going up to salt lake. normally it stays around 17 reguardless if im empty or pulling a trailer but this was a little heavy and there is some good sized hills on that run. Im also thinking that ultra low sulfer fuel isnt as good for mileage but it might be in my head.

14.5? @ 26,900lbs with a 7.3 and a slush box?

:laughing::laughing::laughing::laughing::laughing: :laughing:

you're full of shit. and most likely running illegal since you're over 26k

some states let you run to whatever your plates say regardless of the vehicle ratings, but as far as i know, no states let you run over 26k without a Class A CDL (minus a few RV regulations but that ain't an RV)

i got about 9.5 this weekend running down to VA. and back.. pulling a 8x10' enclosed utility trailer loaded to the max ! a baby grand piano a full couch a queen bed about 20 boxes of shit.. plus a chest freezer in the truck bed.

Oh my truck's a 2003 ram 1500 4x4 Crew cab Hemi

my 89 d250 with the ctd gets about 25 unloaded and about 23 loaded. this past weekend i tipped the scale at 16k at got about 22mpg on a 300 mile round trip. not bad for an old pos.

'02 LB7 with EFI. 33" tires.

that trip we averaged 11-12mpg down and back (from Chicago to Hot Springs AR). that was with the ac cranked since it was over 105* in AR. we were running between 70-80mph the whole way. not too bad I guess.

GPS confirmed :flipoff2:. Stop crying because your gasser gets 8mpg. Plus i have made several 4400 mile round trips to California and back and got about 20-25 mpg consistantly regardless of being loaded or unloaded. Worse i seen was prolly about 15mpg pulling up the sierra's. 1st gens are known for awesome milage, plus i got the mods to back up my mpg readings.

He has a modded 2nd gen CTD.

I had a first gen ('92 5 spd 3.55s) I was happy to 18-19 empty on the highway. For driving empty I was happier with my Ranger. (23 or so).

That kind of mileage draggin anything is amazing.

That being said I do get 8 mpg with my gasser. Gas is cheap, I don't get hung up on mileage, but useability.

cool, i was getting about 20 unloaded when i first got my truck, but after a hx35 with a 16cm^3 turbine housing, straight 4 inch, BHAF, and a few pump tweaks i was seeing 25mpg and alot lower egt's across the board.

Unless i missed it.......I didnt see anybody reply thats towing with the Triton 5.4 V8??

I've got an '01 Expedition w/ 5.4, 3.55 gears & AWD. Completely stock I got about 8 - 8.5 MPG towing 6k running about 75 MPH.

Now with intake, cat-back & XCal 2 w/ a tow tune and I got 10.5 MPG towing the same load on the same trip. I finally just re-geared to 4.56 to tow better & I expect mileage will go up a little bit more yet...

I have a modded second gen CTD. So your sayin that you can hook up to a 10,000 pound trailer and get over 20mpg? Im a member of TDR and I did a search on best milage for a 2wd first gen. Empty your at the top of what they claim but loaded your off the map. Better call Ripley's cause youve got one in ten million.

Yeah man I can't believe most of the numbers in this thread... like the guy above with a 5.4 in a big ass expedition w/ 3.55's towing @ 75mph and he still got 8-8.5? Thats what I get towing with my Big Block, 4L80 and 4.10's... I just find most of this hard to believe...

One of the things you'll note with Dan's rig is he built his trailer very low and close to the Ex avoiding a lotof drag. I notice a tremendous difference in mileage towing with my Dodge on a 34' trailer with the double stack frame compared to the short low single car hauler. AT least 15% difference

True and his rig is lighter than mine... his was just an example... I'm just blown away by some of these claims...

I have an 01 Ford Supercrew with a 5.4L and 3:55's and those numbers on MPG dont appear to be exaggerated. That Amigo looks lighter then my TJ and I can get the same gas mileage. Yeah towing with 3:55's sucks ballz. I can't hold my speed on the slightest incline, it sounds and feels like the tranny is working it's fawking ass off, and it's an old 2v gas motor.

Mine has a CAI and exhaust. I towed a 2004 Tige 22v wake board boat from Norman, OK to Tulsa, OK with the my Ford. I filled the truck completely up with gas (at or around 22 gallons, manual says 24 I think.) and tried to keep the 75mph speed limit the whole way. I got around 200-220 to the tank which averaged out 9-10MPG.

I guess its a combo of a few things... my BB is very thirsty even unloaded and I'm near 10k where as he was around 6k-7k...that extra 3k-4k must make a big difference :)

ok, im on TDR too and been with TDR a long time, what does that have to do with anything? most of the 1st gen guys do mods for power. i have done mods for the best mileage and lowest egt's.

i also said the mpg reading was round trip, so my return home prolly was 16-18mpg. trip out prolly was about 25mpg, no hills cruising at 65mph.

Definition of round trip:
A trip from one place to another and back over the same route


No hills, same path, yet 9 miles to the gallon difference....:confused: Your constant edits to your prior posts make it clear that you’re back pedaling so I’m done hijacking the thread with this debate.

If you’re going to post bull on pirate, someone is going to call you on it. Today it was me, tomorrow it will be someone else. Nothing personal.

Mike

your being a douche bag, i edited to put in more info after re-reading. stop being pissy cause my 1st gen kicks your 2nd in mileage.

I get between 8-10mpg loaded but heavier than most :eek:. The one load of hay I was close to 45K gross and the tires were around 34K gross. I am between 400-425rwhp towing those loads. I was careless and left it close to 500rwhp for a while and it cost me a motor :(

Yeah man I can't believe most of the numbers in this thread... like the guy above with a 5.4 in a big ass expedition w/ 3.55's towing @ 75mph and he still got 8-8.5?

And you think that is an exaggeration? Dude, that sucks balls. :shaking: You should be picking on the guys claiming 20+ in their diesel 1-tons... :laughing:

But, just to correct myself... I said (from memory) 8 - 8.5 stock. I looked up a post I made elsewhere (http://www.f150online.com/forums/showthread.php?t=288235) back when this was all fresh in my mind. It was actually 7.8, so I guess I "exaggerated" by 2/10's of a MPG. The 10.5 I got on the last trip is accurate though...

I have a 5.6 liter with 2.93's, and I usually stay double digits pulling a 7k trailer @70-75, never dropped below 9. I got about 12 pulling a 4.5-5k pound load @ 70-75. regular highway is 16.5-18. I don't know why his is hard to believe.

2000 F350 7.3 (SCMT at 70hp with 4" straight pipe and Donaldson intake) 2wd 4R100 with 3.73 in the diff. I get between 11-13 loaded like this:

I get about 14-15 with just the camper alone or just the boat or Zuk on a trailer without the camper. On my last trip to Tellico I got 14 going uphill towing my Samurai. 15 on the way back.

These figures are based on keeping the tach right at 2k which is about 68 mph on the highway.

Empty I can get about 20 on the highway. The key to a 7.3 is keep the tach under 2k.

I always love to read the number's some claim to have in these threads. No bull shit numbers on a 2006 Dodge mega cab 4x4, cummins, auto, with a Bully dog thriple dog and nothing else, setting on performance, stock tires and no lift. 19.5 mpg on the highway unloaded and no trailer. With 18ft. car trailer and comp. buggy, tools, welder and spare parts, we get 13.5 mpg on the freeway at 75 mph. Truck has 33,000 miles on it now after this season. I never touch the programer at all, it is always set were it is now. I like the Dodge so far over the Ford I traded off but the seats suck ass:D

05 F250 V-10 gasser, 4.10's - Pulls like a horse, but drinks gas like water! Around town - 10mpg, HIghway, no load - 12.5mpg, Loaded (8K trailer and load) 7.5mpg running between 73-76 mph. Gas tank is way to small when pulling , have to stop every 200 miles to be safe.

On a funny note after seeing some of these wacked numbers: Where I used to work every time someone got a new truck they were always bragging about the mpg and whatever. Here is what we used to do: For about the first month we would add a little gas each week to their tank without them knowing and they could not believe the numbers they were getting; Then the fun part, after about a month or so we would siphon off a few gallons each week just to mess with them. Drove em crazy trying to figure out what was wrong.:shaking:

I always love to read the number's some claim to have in these threads.

You sometimes got to wonder....

I realy only use my 91.5 CTD dodge for towing a 20ft gooseneck with a single 5000lb rig on it. It's a 4wd standard cab, manual with stock sized tires. The valley floor around here is at 4500ft so we are at high altitude with a lot of passes. I usualy run around 65-70mph and rarly have it pull me below 55-60mph on the hills.

I average around 15mpg while towing.

I have averaged 19mpg in my last 2 tanks. That is very conservative driving. I haven't towed with it yet, but will in a few weeks.

I have an 04 Chevy Silverado Duramax/Allison.
