I don't think you are in bad shape. I think might be a difference in
perception. I believe the compressor pumps the tank to about 120 psi (maybe it
turns on at 100 and off at 120?), but the bags should require less, an mine take
about 75 to lift the back of my admittedly light 23'. Although I usually use
shop air to pressurize the system before a trip, I've also used the on-board
compressor and it doesn't take an inordinate amount of time. In normal use, the
bags take very little air volume, so the standard compressor is certainly
"adequate." At the storage location as long as you can get the engine started
you should be able to get enough air pressure to lift the back.

I did look in my manuals, but I didn't find it in either the Jimmy
manual or the Motorhome manual. Did that before I asked. I'm at home
now (got hot, had to use the facilities and my coach isn't exactly
ready for that yet). I needed refilling my compressor anyway (no power
at my storage location).
Great. My cheap Harbor Freight air compressor only goes up to 100 psi.
If the bag and the tank are both saying "40psi" no air is going to go
from the tank to the tire. I'm going to have to keep refilling my 3
gallon compressor until I get that air bag up.
So a 3 gallon air compressor is woefully underpowered for this type of
task, correct?
