Stabilize camper with truck camper jacks?

It may work but I think you're going to have a problem with the weight of the 'C' compared to a truck camper plus the front corners of the camper body are probably not reinforced to handle being lifted up there and unless the back is square how are you going to mount them?

As long as you don't try to use the jacks for lifting/leveling, if you can mount them securely, the idea should work for mild stabilizing.

Another option could be to mount a pair of swing-up, boat trailer style, tongue jacks, one at the end of each rear frame rail (remove bumper and build a heavier duty one to mount the jacks to). Same could be done up front, except mount them on extensions, to each side of a front receiver hitch.

Screw-type scissor jacks under the frame rails could be another option, like travel trailers use for stabilizing.

I'm sure it could be done but I don't think you would have a really big cost savings. For a new set of Rieco electric Jacks with a controller is going to cost over $2000. Then you have to make sure you have braced the corners enough to handle the stress. Plus the work of installing.

You could have a set of HWH installed by HWH for a little over $3000. These are fastened to the frame of the chassis and are going to be a lot stronger than the camper jacks and not put the stress on the body of the RV shell. Most camper jacks are rated at 2,500# per jack where the HWH are rated at over 7,000# per jack on the light weight ones. I had a quote thru a dealer close to the HWH factory for a factory install for $3200. If you are handy you could install them yourself and save some money.

Sure you could put them on if you desired to have them sticking out the side of the coach instead of tucked up under the coach. That would be up to you as almost anything can be done if a person is determined enough to do it.

I had a pair similar to these ( Husky 76862 24 Stabilizing Scissor Jack - Set of 2 ) that I just looked at on Amazon.com bolted to the frame behind the rear axle. Since a MH frame is in further than a trailer I have to reach in with my 18v cordless drill and raise or lower them. Once I get them down with the drill I adjust them tighter with the supplied wrench. Just having them on the rear really makes a big difference in how stable the MH is. No more complaints from the DW. I use this Camco 57363 Leveling Scissor Jack Socket with my drill. Dick
