I found by usind some large or stacked blocking under the landing gear and rear stabilizers, and taking it up about an inch to inch and a half on the springs takes just enough wieght off the wheels to drastically reduce the bouncing, just a little side to side motion remains.
what I found also was setting up with a full tank of water and outside stuff still inside, as the weight of the unit changed the springs would lift the stabilizers enough to render them redundant, so if you have patio funiture and bikes or anything else more than a few pounds (which adds up) unload them first.
and no my unit did not twist up like a pretzel or fold up like a V amazingly enough
