level trailer, not tail dragging is good... adjust the hitch ball on the shank down...
if you have chain links on the WDH hitch torsion bars, you may have to do one less link...
as mentioned, measure the bottom of the front TV fender at the center of the wheel from the ground before hitching, then adjust the torsion bars to get back close to that same height after you hitch up your TT... my 1500 RAM, goes up 1.5 inches after dropping the TT on the hitch ball, but after the torsion bars are adjusted and hooked up, the measurement goes back down to within 1/4 to 1/2 inches of the original measurement and tows great.
Stepping back and looking while parked in a flat parking lot, the whole rig looks to be level.
