: Modifying dump trailer to haul rig

My dump trailer was not wide enough to haul my 7' wide Scout. I want to be able to use the dump when I want and use the axle and frame to haul my junk when needed. I don't have room for another trailer, hence the dual purpose change over. I pulled the dump box. and started the frame exension. Onlt pic I could find full of concrete.

Frame extesions being added. Still need to trim to length.

Is it a single or duel axle?

Dual axle and brakes on all fours. The bigger 12" ones too:D

Thinking about it. Might have been easier to make a new "dump" bed for it.

Make a flatbed, or even a slight beaver-tail deck that bolts right in place of the dump bed you took off. Since your beds already 12' long, make a 14' or so "flat" bed and it will probably reach the ground for a tilt deck.

Make it just as wide at the fenders on the trailer (so probably 8' wide I would guess) with drive-over fenders. No modifying the trailer's frame then. Just pull the dump box off, put your trailer deck on and rock it. Or if you wanted the "trailer" bed to be lighter/easier to store/easier to handle. Make it two 14' "planks" rather than a full deck. With some detachable cross members.

Just thinking out loud. Can't tell enough from your pictures to see what you have in mind. Looks bolt-on/detachable.

The dump box is 10' and I had made a flat extension for that. Thats how I got my Scouts home:D That has worked for years on smaller cars and trucks.

I like the idea of the flatbed. But I started this project last weekend and need something workable by this weekend for an up comming trip the following weekend.:eek: I took a pic this morning from the front.
I will brace the rear with some lighter stuff and then need to figure out what to drive on.

Would be great to find some of this stuff ( but can't find it anywhere near me)

OK farted around all day Sat. getting no where fast. Tossed around a lot of ideas and tried a few. Keep in mind I'm trying to use steel I have vs spending money I don't really have. Making in bolt together, so I can have my dump trailer back when needed. Also time and effort for the conversion has played through my mind over and over. As I don't what this to be an all day conversion process.
I would have started a tilt bed if I had the steel. :p
Sunday, I picked a plan and just started building. Basically just going for it. No pic's is lame, some to come later. I still need to get the Scout on the trailer to figured out where I want the D rings.

I have thought of the same thing. I was going to have removable sides. How are you going to dump after you add to the rear? Are you going to move the box back or make the box longer?

My dump box is only 6' wide 10' long and is fully welded, even the sides. It holds stock Scouts and Jeeps with an extension that plugs into the rear of the box making the box 12' long. My rock crawler is 7' wide, hence a change was needed.
This will be a conversion process that will take a couple hours to complete each time. Might get faster after I've done it once or twice. If I want to use the dump trailer, the flat bed has to come off. The box came off real easy, two hinge pins and one ram pin. The flat bed part is bolted on, and will take longer to remove and add then the dump box.
There are 6 bolts on each side holding on the frame extensions, plus a bunch of bolts holding in the cross members.

Here a couple pic's. I had some 2" C channel and welded on some small extenstions that I can use to bolt in cross memebers. Again using what I have on hand for this. What not in the pic is where the trailer is going to be wider. I will weld on C channel to the rear frame rails ( grey) adding about 8" to each side. In the front, it will be different and will be easier to explain once I post some more pic's

This is awesome! I love the idea of a dual purpose trailer

I have always thought that one of the deckover dumps with drop down sides (Mirage, PJ etc.) would make a great multipurpose trailer:

I like those deck overs and removable sides. Great for fork lift access. I like a low deck as I can get most items in the trailer.

Here's the plan for the front, just need to pick up some steel as I don't have any 2.5" and 2" receiver tubing on hand. Basically add some 2.5" to the frame and slide in some 2" extensions. The 2.5" tube will still be under the dump bed so I won't see it when done.

Edit... Forgot to mention, that work got in the way and I won't be wheeling this weekend :( So the trailer project has slowed down. From a need it now, to get it ready.

Got the front bars added. I was a bit short on steel, so the front tapers in 2" Which is fine. Once the wood is added it will look fine.

Had to work today vs being in Hollister:mad3:

Is it my eyes, or do you axles look to have a slight bow in them.

Good eye, yes they are arched from the factory. I assume so they can carry the rated load. Makes since if you think about it. As the weight pushes the tires up the arch flattens out and support the load.

I was able to work on it after work and got the last cross member support added in . I drilled the other side for the extension support, and bolted that in place. I still need to add the rear support on the outside of the frame rails and then I'm ready to add the cross members and the first 2x10. Once that is done I can load the Scout and check where the D rings go. Hopefully it all works as planed.

Just need to decide if the rear should be as wide as the tires. I was thinking just 4" wider than the Scout. The difference would be an extra 4" on each side.

Subscribed !.
Been toying with the idea of doing the exact same thing as the new place doesn't have a lot of room in the side yard for a full width trailer. Drive over fenders and widening the trailer to be just wide enough.....

What's the overall side wall to sidewall width of that thing?

The trailer is 96" 8') outside of tires. I spent a bit of time on the trailer today, but never got the Scout load, as we had to go places.

Welded up the outside extension for the rear and started adding cross members, only to find out I did not have as much tubing on hand as I thought. I bought 4 2x10's 12 feet long. They are Douglas fir, so I painted them with some primer to slow down the drying and keep them from cracking. I would need 4 more boards to do a complete deck, still pondering that idea.

Edit.. Here a current pic. I was able to get 2 hours of free time, and I welded on some bracket to support and bolt down the 2x10. I figured the board would cup so a couple more bots added.
It's basically ready for a test load to figure out the where the D rings or other tie down attachment points need to be added.

Ok seems like I made this minor build a career. but it's ready to be painting.

Could not find my camera when the Scout was on it. After paint, powder coat and chrome.:homer:

Had some time after dinner and mixed up some paint and my stupid gun would not work.:mad3: I got it working enough that paint came out. About the crappiest paint job on the planet. But at least you can't tell from a 100 yards away.:homer: Need to added some lights, put the decking back on. Hopefully by the weekend have the Scout loaded and go for a test drive.

Took it out for a test drive and it was stable at 55-60 MPH.:smokin: Can my truck can pull it up a hill has yet to be determined.

Raised the brake line so the chain was easier to wrap around the axle

Alrighty then, looks good. I decided to check this out as i just sold my car 16' trailer but i still have a 18' equipment trailer and a 6X10 dump trailer. I am thinking of doing what you did but i was wondering why you didnt build a flat bed that attached to the stock frame like the dump did. Essentially it would take the same amount of time to install and remove as the factory dump bed and you could even attach the ram and make the flat bed incline if you wanted. You didnt move the axles right, you left them in the stock location? If i do this like i just mentioned i guess some locks up front wouldnt hurt to keep it from tilting.
