Something sound wrong.... if you are relatively level wheel to wheel, utilizing lego blocks, boards, Anderson edge, whatever..., then level front to rear with the front jacks (or tongue jack for a bumper-pull). After that, a couple of stabilizers should keep it relatively level. If you need to do more than that, then it sounds like some serious frame problems....
