As I was going over my list of topics I wanted to cover for these ‘year in review’ posts and realized I have been grouping items together OH NOOOO – how will I come up with 18 posts? Today I am self editing and showing you the air compression system and saving the steering for tomorrow!
The GMC Motorhome has front wheel drive with a unique, automatic leveling, load adjustable air suspension system that can be set manually when parked or set to self-level when driving. These designs provide better traction and more room for living, since you are sitting on top of the front wheels instead of them being back a bit and having the wheel wells impede into the living space. Better traction and more living space is a big deal for fulltime RV living.
The air suspension system operates using a compressor, valves, and controls in conjunction with air springs, all things that need to be replaced overtime. Thankfully getting to the actual air bags is easy, you just remove the T-skirt, of course like any other repair ‘easy’ is relative.
After 44 years there was certainly work to be done to give us a smooth ride. There are two schools of advice about the air bags. We chose to replace the Hensley Air Bags with Sully bags.
We also replaced the air compressor with a Viair compressor. To quote the Viair description – The VIAIR 300P Portable Compressor offers inflation of up to 33-inch tires at a rapid rate, and operation at up to 150 PSI for up to 15 continuous minutes at a time….. We can use the Viair to fill our tires if needed or pool toys!
We knew we had a small leak in our compression lines, somewhere. When checking with a bottle of soapy water we saw where we had a small leak behind the compressor switches in the cab area that just took a little tightening. Whew…. truly an easy fix!

Our New Neighborhood 2023 
Sweet looking GMC Motorhome. I find it way more attractive than the Winnebago Brave or Chieftain, I also find it way more attractive than what’s being offered today.

We feel the same, plus not made out of wood (or wood substitute!) so leaking and mildew less of an issue.

I would think mildew could be a with any vehicle, particularly if left out in the elements.
