HELP RV Stuck, Rear Air bags won't inflate

I have a suspision that you are correct in that you did not give it enough time to build pressure. Pressure builds slow at first as it must double the volumn in the tank to double the pressure which from a start would get it to 15 psi which is not much.

I was hoping we were right on that, but unfortunately not. The melting snow was starting to pool on the roof. I have the engine out of it, and therefore can't hook up the battery. I isolated the Jet Ride wiring and hooked it up to the battery so I could operate the system.

Compressor ran for a long time but didn't build any pressure. I hooked my compressor up to it until the gauge hit 90 PSI (the compressor shut off pressure according to Jet Co). It pumped the back up to what appeared to be an acceptable right height and all the water drained off of the roof.

I unhooked my air compressor and the Jet Co compressor was still running. Despite this, the gauge slowly creeped down to 0 (or would have had I watched it long enough). So it appears as if there is a leak between the compressor (assuming it's compressing air) and the tank or between the tank and the bag solenoids.

Problem #2 is that the left bag deflates pretty quickly. This morning the left side is on the ground, which in this case is good because the melting snow will continue to drain to that side. So this means that either the bag has a leak (there's a spare in a storage compartment), the solenoid is leaking into the leaky supply system or the line between the solenoid and the bag is leaking.

The good news is that both leaks are big enough that they should be easy to find...that is once I find the time to crawl under there.
