Some time ago I remember reading about someone installing those electric RV leveling jacks on their GMC. I can't locate it via search, so maybe I'm using the wrong search words. My wife doesn't like movement of the GMC when people are going in and out, walking around inside, etc.
I've been using those aluminum WalMart triangle type screw pedestal things that require me to crawl under to ensure they're lifting at appropriate locations. Low cost solutions most welcome! Thanks in advance.

I can't pull up the album on my phone -- search the photo site for leveling jacks and view Jim Wagners project.

I use a small bottle jack, or screw jack to do the same thing. Slide it under the rear boggie, a little pressure lift and the coach is solid, no rocking.

My PO installed a fairly big set of rollers under the rear frame (to keep the frame from bottoming when pulling out of / into parking lots). I just get the tail a little high when I level it at the campground, slide a few bits of wood under the roller (I carry small pieces of 2x8's, 2x4's, and 1x4's). I just stack 'em in until it's close to snug, then let a little air out and voila, the coach is rock-solid. Well, technically it can still move a little if you really hop around up front, but that just never seems to be much of an issue, since I never notice (I really DO notice the back moving without blocks, though that doesn't really bother me too much either).

Those both look viable for stabilizing. Chucks looks like an adapted tongue jack and workable
Neither would be too useful for true leveling as the capacity and travel is probably insufficient
Both Hydraulic and electric levelers are available, even automatic versions. They are expensive and complex to install.
I have never seen a set on a GMC. In fact , they may be too low to use them without modification... Someone can probably weigh in on that
Those with electric only fridges don't have to worry about level quite so much.
The cheapest solution may be trailer type scissor stabilizers. Again, not so much for leveling but for stabilizing.
They do still require manual crankng, but simple to mount

Larry,
I could be wrong (that has happened), but I believe that the coach with the built in jacks was Ted Stinnett. I believe that there is another, but I can't drag that out of the memory just now. Maybe Jim Wagner???
We carry an assortment of wood blocks. If we are going to be someplace for a while (like an international), I will either use the air to lift the coach and set it back down on blocks that I have placed under the bogie or will use the pair of salvaged scissor jacks for the same purpose. I like the blocks better because they won't tip over, but they do take longer to set up.

Chris,
I beg to differ with you, I have seen Chuck's GMC in the flesh and it worked. I knew him, he worked for General Dynamics as an
engineer. He WAS a rocket scientist! He's the guy that came up with the reaction arm braking system.

Oh, Im not knocking Chucks design in the least. The wedge brake is pure genius!
What Im wondering is if it is a trailer tongue jack as it looks to be, most of those have about 2K# capacity. If it isnt. Id be curious what it is.
Is it enough to get both wheels on that side off the ground? Would be very useful for tire changes if the brake was not applied
As far as usefulness for leveling as opposed to stabilizing, it occurs that it would depend how far off level the site is in the first place. If it is fairly close you dont need to put the full wt of the coach on the jack.
