: Converting an RV to a 5th Wheel + trailer.

Does anyone have information on this?

What affect would running the two sets of rear wheels so far apart have?

I’ve heard of this being done, looks like a good idea for me. Why, lets just say the previous owner tore out the entire front dash and wiring, to include the automotive side. I’ve spent way to much time re-doing it, I’m done. I;ve tried to sell the RV, but no takers. I want a 5th wheel with a camper, but they cost over double what I’m asking for the RV.

For the rear, figure I’d get some C channel, fit it inside the RV frame about 5 feet. Weld it solid to the frame. Then pick up another 14B dually rear and run that in the back. (Maybe a Dana 44 front axle instead)
For the font, just cut the whole thing off. Maybe someone sells the front part of a 5th wheel?
What does a 454 with 80K go for? Just in the thinking stages right now.

I don't think that rear axle is going to last very long. Your pivot point for the trailer is gong to be your front axle. This is going to more or less cause your rear axle to be drug sideways everytime you make a turn. This is regaurdless of the fact that the bulk of the wieght for the trailer is going to be hanging out past the rear axle. This is going to cause the tung of the trailer to do some bad chit.


Nice idea but poor execution. now if you were able to move the axles so that you had a dual rear axle under the center of the Jeep you might have something. I'm sure you would have to do some serious stiffening on the RV chasis and the distance between you axle and king pin wouldn't be the best so it would turn like a battle ship but I think that's your best option.

I'm still in the planing phase, and may not ever exicute. But figured I might get some good ideas here. I've seen several large trailers with wheels that are space far apart.

Oyeah, the RV front bumber to rear is 25' long.

What about using the RV front axle for the rear most axle, and have it setup with a spring-return to center (like on a cement truck).

Or, buy a big 5th wheel trailer, and put a slide in camper on the front of it.

Pete I've talked to some who drive a Cement truck, he said most are hydrolic, and that the spring really wouldn;t work in this case. Thanks for the idea.

id buy a 40 foot gooseneck trailer, mount the rv to it via some custom pivoting mounts, and then have space for the jeep behind that! sounds good in my head!

It might work if you used some giant caster wheels on the back. They actually make little 'bed extender' deal for small trucks that has a single caster wheel centered at the very back. Saw one on the highway a while back.

Do you have it set up to pull your truck now? I have seen plenty of guys towing their trucks with campers similar to this. They are towing light rigs with the shortest lightest trailers they could get the truck on. I guess it depends on how fast you wanna go..

If I can't sell the RV I'm thinking of doing the above to it.

You need to keep your axles close together despite what you see on some of the big rigs. How many14k trailers do you see with spread axles? There are reasons.

My camper / hauler is for sale- email me for pics (I'm too much of a dummy to post the pic- someone did it for me before and you could find it if you searched. It's a 21' fifth wheel with a 17' dovetail flatbed behind it. Tows awesome with my 2500 Cummins Dodge.

You can't afford to make what I have for the price I'm willing to sell it for.

What about when the Jeep isn't in on the rear section for towing? Seems like a lot of toung weighthttp://77cj.littlekeylime.com/5thwheelrv2nd.gif

Mr. N- did not get your PM....

Goosenecks/fifthwheels typically run 15-20% hitchweight- If your camper is light enough you can nail this easy. I'm closer to 20% running empty but can easily tune it with the Jeep depending where I put it. Just came back from the SC in Farmington without the Jeep, could tell there was more hitch weight but still off the helper springs on my dodge quadcab shortbed.
