GMC Air Compressor

I have found that I normally set the air pressure to go on a trip and forget
it. My load does not change when driving. My air compressor would cycle on
and off due to leak back in the heads. So installed a switch. In my current
project coach, a 75-26' Avion, I installed a new one bagger from Applied and
have found that I need 35 to 40 lbs pressure to give me the ride height I
want on the road. The only time I touch the pressure is in a campsite to
level. Rather than tackle the compressor/tank/connections/valves issue on
the coach: I have installed the shutoffs-schrader valve combos at each axle
and carry a battery powered hand compressor. It takes me only a short amount
of time to set my desired levels to camp or travel, at a cost of under $100
for both battery and compressor and I have a portable tool to do other
things that need air as well.

Many more GMC's in use today have a modified air ride height system.
Everything from simple Schrader valves, to snakes nests full of extra
lines, gages, and what have you.
It is like 5 blind guys looking at an elephant. Each of them has hold
of a different part of the animal, but, no one knows what the whole animal
looks like.
Having 4 different configurations installed over the years by GMC
doesn't help matters much, either.
The underlying principle of all of the systems is to vary the ride height
of the coach by managing the air pressure in the bags.

This must be one of the variations that are apparent with my light 73 - 23. When the system is tight, the compressor will almost never run while on
the road. But, after putting on 40~47 gallons (~300#) of fuel, the compressor is almost always on when leaving the fuel stop.

I did have to disable the system at one time as the result of a component failure. I could feel the difference with the change in fuel load. I can
feel it with the system active, but it makes very little difference.

I would love to be able to swap in a Micro-Air just to try it, but I have other issues to deal with for the near term.

Jim,
Don't you supply a remote controlled air system?
Have seen several customers in our shop that are satisfied with the unit.

Yes, you market it. The only way I sell them is if i install them.
Otherwise, they purchase them through you.
