Newell rebuilt the check valves on the front slides today. Right now I am running a test with the 120V compressor off, and the air dumped from the front tank. We are looking to see how long the seals will stay inflated. (The same test before working on the check valves showed that the front two seals went completely down overnight).

If the seals will stay inflated for days/weeks with the 120V supply off, I will be less worried.

I really liked Forests suggestion of an aux pump. I may start thinking along those lines. (Newell suggested plumbing in my pancake air compressor, but that seems a little bulky/clunky to me).
