Always interesting when the OP does not give feedback, but maybe some folks are not as obsessive about the forums as I am....
My guess, totally a guess is that somehow the hitch is not set up properly, one side of the weight distribution/sway control arms being adjusted to a different length than the other.
The way I have found to check this is to drive the TV and AS to a large level parking lot, straight forward, and then adjust the bars precisely.
Another issue could be tire pressures, and if one wants to compensate for road crown, there are some ways to do this with right left variations on the TV. My moho had about 3 lbs. different R to L, i.e., 110 on road side, 113 curb side....Steer axle, 100, 102 in rear, duals and TAG.
