I installed my basic Air-Lift kit over the weekend.  It lifts an empty
Westy about 1/4" with 25 psig in each bladder.  I looped the lines behind
the springs so the valve stem faces straight out  in the frame above the
tire.  (There were holes there already.)  Couldn't honestly notice much
difference with empty van, but I'm sure it will help once loaded down.  (I
could see a little more out the back window!)  No leaks overnight.   Stems
may see some mud at this location, but with caps should be OK.  Seemed like
a real good place to put the valve stem until I see how they work.  I may
eventually tee them together and run the tubing to the back seat
compartment.
