Some on here seem to have lost grasp of common sense and the laws of physics. Where are these vector forces coming from? If a MH is on the jacks, it should not be moving. mssmith; of course it is going to move, just as it would if it was not on the jacks and you took the brakes off. If the ground, or area you are trying to level on is that unstable, what are you doing driving your MH on it?
We probably have used our leveling system in some of the worst conditions, and areas of anyone. We use to snowmobile, pulling the 2 sled trailer with the MH. The last time we went, the snow park and campground were not plowed, and I was not paying enough attention. Went down a 35 deg. ramp into the campground and was stuck. Had crappy cable changes that kept throwing off. Anyway, finely got to the snow park and someone was parked in the inlet road. Stuck again, put the chains back on and tried to back up a 30 deg road, but missed road, and was stuck again. Got someone to take me into Les Schwab to get real chains. Used the leveling jacks again, on the 30 deg angle, in large rocks to raise the rear of the MH to get the chains on. The front jacks were down and manually raised the rear. It did move forward about 1.5 feet before it anchored. Got the real chains on and drove out the road that I had plowed coming in, and parked for the night at another snow park not far from there. We leveled up on compact snow and the front wheels were off the snow slightly. It was solid as I tried to shake it and it never moved for the time we where there. This was REAL WORLD experience, either Fleetwood makes great choices in the leveling systems or the systems them selves are very robust.
Wow! I think you are very lucky something didn't break and no one got hurt.
The only confusion here is if the back wheels stay on the ground then they take up the side load. If you raise the rear wheels off the ground there is nothing to take the side loads of an incline however small or large they might be. The evidence of the side load is 1.5 ft you mention. You would be relying entirely on the integrity of the mounting system of the jacks. Whether they would sustain that is a guess and I'm certain the manufacturer of the jacks would consider that to be outside of their intended use.
The OP has a problem with his system and needs to get it fixed.
