Troy, I have this kit on my Westy but not for what you propose.  I carry a Kawa Sherpa, close to 300 lbs, motorcycle on a bumper hitch and the air lifts were installed to jack up the rear when the motorcycle is on board.  Works perfect, bags pumped to 50 lbs. when motorcycle is on, 5 lbs when off.  I plumbed them separately as they can be used to level the van somewhat in uneven camp spots.  Levelling your van due to uneven spring wear can be done but I would recommend getting new springs.  Van Cafe now has new ones availed and I have two sets of OEM Westy ones that I brought back from Germany.

I'm just wondering if one of these airlift suspension kits could equalize the weight, and at the same time even out the rear, or if that would require new springs and/or spacers.
