When we had a tt and with our current 5er the first thing I did was to level the rig at home and install small bubble levels on the front left corner of the rig. I use these to estimate the amount of boards or what ever to put under the low side. I plug in, unhitch, level front to rear, put all stabilizers down then put slides out. Yes I have a little wiggle, but it does not bother us. If it is to much I check the stabilizer tightness and the chock tightness. Sometimes I find them loser than when first set up. I don't us Roto-chocks or king pin stabilizer.
