He stated that if the coach leaned to one side or the other when the tanks were full to adjust that sides helper springs more to try and even out the coach.
From what I read on Hellwig's site, their helpers provide side-to-side "load leveling" which makes sense, since front-to-rear leveling would imply going above the rated capacity of the springs and axle.
We sit a little tail-high, so help definitely not needed at the rear. The side-to-side seems right or close to it. A full black tank would load the right side down, but we don't run with it full anyway.
