I went out and jacked up the parts coach today.
I put it on jackstands, but because of it's location, I had to position the rear jacks just behind the rear wheel on the drivers side.
When I went to leave, it did a double take, and there appeared to be a buckle on the body, south of the window, and just a little in front of the rear wheel well opening.
The coach is level. I jacked the front up first, placed jackstands under the lap between the front subframe and the main frame. I generally place the rear jacks in front of the bogies.
Is this a frame problem, a SUT (oops, that's what software designers call a "stupid user trick") based on the jack stand location, or the frame/body pads?
Thanks.

Dolph, the proper place to support the rear of the coach is under the bogie
boxes. I have noticed the same thing you descrbe on coaches when I have
placed jack stands under the frame behind the rear tires. Another good
support method on the rear is ramps under both tires on each side of the
coach. JWID.

Dolph,
My not-so-WAG is that the main frame rails are severely rusted where
they're reinforced for the rear suspension. The two sandwiched C-channels
there collect moisture & salt rust like crazy. The jack stands are putting
the body in compression; if you move the rear ones forward of the middle
wheels, it will be in tension and less likely to buckle, IMHO.

Overall the GMC body is very stiff. However, it is not at all unusual for vehicle bodies to distort while jacking. There were many vehicles in the 60's and 70's where the doors wouldn't open while jacked. Even some newer vehicles exhibit changes in door gaps while jacking. Hopefully it returns to it's natural state.

Ken,
I concur with you. I have new rails, and I've had to jack stand (temporarily) behind rear tire, with no body buckle.
The top flange, for about 12" at the bogie mount under the isolation strip, was totally rusted out. As in not there, but it was not visible because the isolation strip covered it completely.
When replacing pads, I'd think that using several feet of 4 x 4 to spread the lift force (with 2 jacks) would be a better way to do it.
When we avoid the mistake we might have made, we sometimes make the mistake that we might have avoided.

Does this lead to the tilted cabinets in the Palm Beach?

I've seen lots of pad replacement discussions. Is it purely ride related?

Dolph,
Yes, that's my understanding. It removes some of the ride harshness. Crushed or missing pads can be responsible for pinching hoses between the body and chassis, too

I wouldn't say pads affect the ride, but they sure do affect the noise
level. With bad pads the coach sounds like a wagon load of junk crossing a
railroad track -- and that's with a fully remodeled interior & solid frame.
With new pads, the same coach sounds like a new Cadillac (not quite like a
Lexus though).

Tilted cabinets??? Most decrepit cabinets I've seen were either loose from
the ceiling or joints were coming apart. Simply age and lack of
rejuvenation -- unless there's obvious water or other damage, of course.

Thanks for all the input on this.... it turns out the frame is fine (it's a California coach, that spent a few months in IL and then here), and I found the dent in on the body (so maybe a "buckle" was the wrong term) had a very mechanical cause.
"Peeling the onion" on my coach has been an experience, and I had an un-necessary "oh s--t" moment.
Back to figuring out what I want to do with the master cylinder and brakes.
Thanks again for all the direct input and experiences.

I've had mine up on jackstands aft of the rear wheel with no ill effects. Makes it real easy to work on the coach. My Frame is AZ-CA, however.

Sometimes, it's where you keep the coach.
The driving coach is within sight, and not a problem.
The parts coach is next to a building that I own, and near a school.
The local boys have been slamming into the side of the parts coach, and causing the bow. in the aluminum.
Beware.... little old ladies still look out their windows, and now they have smartphones.
