TireFryerSS If the op is still considering this, then I would suggest going the gooseneck route to make it tow better.

therabbittree I've been looking into fabricating a dump trailer for the same reasons every one here mentioned.. I have 2 hoist options :a nice scissor lift hoist rated for 12,000 lbs, or I have a multi stage piston from a small dump truck that I could fab up as a hoist??? I want to use.. I'd like it to be a deck over and pretty long so I could tow cars and equipment. Just trying to figure out the specs.. I definately want 8 lug 7000 lb or bigger axles. Maybe even step up to 17.5 or 19.5 wheels. I want electric over hydraulic disk brakes. I'd like to fab the dump floor from either hardox or reg steel with some Big truck dump trailer liner. Ir would be neat to try to do a frameless dump but not sure i could do it with out a traveling rear suspension setup...ie a frameless setup on a normal tractor trailer has a center point or air ride with the rear axle at the back of the trailer.. but a normal small dump would have the axles in the middle to keep the tongue weight in control etc. it would be nice to have a 20' deck with amaybe a partila dump like a split tilt trailer.
Any ideas?
Thanks,
Deo

billy bones You could build something similar to a Switch-n-go truck body. No loader required to change your box/deck.

blakeape I have a 14K 14'x8' dump trailer that I have hauled all sorts of things in, gravel, garbage, dirt, lumber, my Kubota L35 tractor (7000 lbs) and numerous vehicles including my 1 Ton Tacoma (5500 lbs). The tractor and Tacoma fit but due to the high center of gravity and the short overall length do not tow wonderfully. My Taco has the back of the cab cut out so I have to mount it with the front bumper forward which gives me excessive tongue weight. The tractor/dump trailer combo is handy as hell, but doesn't tow very well either. I can go to a job, drop the tractor, go get 4 yards of crush gravel, come back, dump it, spread it, load up the tractor and head home. I also have an 18 ft 10k car hauler that tows way better. Around town, dump trailer is fine, for long road trips the car hauler blows the dump away. That being said, the dump is handy as hell, has towed my Tacoma from MT to the Rubicon and it was my only trailer for 4 years.

rockcrawln I started looking into the dimensions and I think I can do the whole take the box off and put a deck on.

If I setup the deck so that it bolts/pins on and goes over/around the hyd power unit I shouldn't have any problem getting an 18' deck with close to the right axle location.

Based off Big Tex's website (I don't think I would ever buy a trailer from them but they had dimensions) their 10k lb car trailer weighs about 2500 lbs, a 12' dump trailer weighs around 3700 lbs. I figure I should be able to convert the dump to a trailer and keep the same curb weight (but probably less) which gives me about 6000 to play with for payload. Does this sound reasonable?

If I did something like this I would make sure I could do the swap in less than 30 minutes with the use of a tractor. I don't think I will be able to make it tilt though due to the location of the pivot on the dump trailer unless I made the trailer 20+' long.

YellowSub1962 I edited my post, I left out a "0" and put 1001 instead of "10,001" sorry if that caused any confusion.

comeoutswingin They do make flatbed car haulers, that hoist just like a dump trailer does....

i use the neighbors 14ft dump all the time.. it; never came with ramps.. but then again it's not a heavy duty dump trailer.. 6 lug axles and surge brakes

rockcrawln I like the idea of pulling the box off and and making a flat bed. Eventually I will have a crawler loader so I should be able to lift the box/deck off easily.

qumanchew My dad has a 14' dump that I've used a few times. The biggest thing I don't like about hauling a vehicle is the lack of length to adjust you're tongue weight,Even with my Bronco II. As has been mentioned before the weight and reaching the tiedowns suck. You have to climb in and out to reach them.

you might want to rethink that, because it's not entirely true.

CA considers any tag trailer with a GVWR over 10001 that is not an RV a commercial vehicle, regardless of how it's used and regardless of what it weighs empty. If you're buying new, have them derate it to 9999 and label it a utility trailer on the MCO - otherwise you need dot#s, stop at scales, etc... This also means you're buying a 14K rated trailer and only legally able to put ~6K on/in it instead of ~12K

One technicality you could be busted for is transporting an uncovered load. Police around here tend to frown on anything openly transported in a dump body. Gravel, firewood, cars, Igloo cooler. Dump truck or trailer, doesn't matter. Put a tarp over whatever you are carrying, magically everything is ok

4x4prepper The disadvantages are:

1 - weighs a lot more

2 - higher deck height

3 - worse aerodynamics because of the big square front

4 - no ramp provisions

5 - harder to use a winch in the front to pull something on.

Unlike a roll back, you are not going to be raising the bed and then trying to pull something on.

That being said, just buy one with stake sides, winch to the front, attach straps from the side for the front, and pull it back with the back straps to tension it.

If I needed a dump trailer I would certainly use it for double duty as a car hauler. If you are using 10K straps or sch 70 3/8 chain and have four corners tied down, I don't see how you can get ticketed for anything.

By the time one were to buy that set up, you could just have 2 trailers and wouldnt have to do shit but hook up and drive away.

TireFryerSS I have 7x14 hyd. dump trailer...the biggest reason it wouldnt make a good hauler is because of the weight. Mine weighs in around 3500lbs. compare that to a car hauler, especially when behind a BBC. Also it might just be me, but the damn thing feels like it makes my Super Duty work harder to pull it around than my 30ft gooseneck which weighs something like 6000lbs.

I've gone round and round trying to make one trailer do everything, and it just doesnt work. In fact Im thinking about adding a 20ft gooseneck car hauler because of how easy they tow.

Investing the $$ in 2 trailers isnt a bad thing. You'll be happier in the long run.
03-29-2012 08:07 PM
Joe_88k5 I had the same idea, swapping between the dump and a deck. My idea for swapping was to build legs that would hold the bed up over the trailer... like what the highway departments around here use to hold the salters during the summer when they use the trucks as dump trucks.

Raise the bed with the cylinder and attach the front legs
Release cylinder pressure and unpin
Attach rear legs (jacks) and take the weight off enough to pull the pins
Pull the trailer out from under the bed

It would be a bit of a process but isn't something I'd be doing very often and I don't have the luxury of heavy equipment.

It would be nice to only have to pay for one trailer registration, especially since NY seems to raise them every year.

Mini-ex is what i would use. A good size tractor may be able to do it too depending on the weight of the bed. A cheap easy way i thought of too was the jacks for an in bed camper. You could slip those on a mount welded to the sides and hand crank each side up off the frame.

Most dump trailers will generally have a substantial d ring welded in each corner of the box from the manufacturer because hauling a bobcat in one is pretty typical.
03-26-2012 06:51 PM
Redfin Dont see how they could bitch unless they were over the gvw. Im thinkin about using my v30 dump to haul my buggy.
03-26-2012 06:42 PM
steved Around here, the local police (southeast PA) prey on guys using dump trailers for car trailers...I often wonder how close the GVW is since those types of trailers weigh more than most car trailers? Probably depends on the area, but I've seen at least three dumps with cars pulled over on my commute over the years. I have thought it would be a cool dual-purpose trailer.
