Quad Bag turns to Tri
- Thread starter billvv
- Start date
The unit is desined to isolate the leaking bag and increase pressure on the good bag with the Air Manifolds.
I know we have done it with a flat tire also.
We stock those bags, but he being in CANADA, he is not able to aquire them easily..

Hey!
That was me having issues yesterday…
Thank you VERY much to @Jimkanomata for taking the time to talk me through this. Jim even called me back later on to give some additional advice. VERY helpful.
Thanks also to @billvv for taking the time to discuss options while he was getting settled at the rally and again later on, once we made it ourselves! Two others from the rally (Debb and Mike, with the GMC Cascaders) went back with me to GMC and ensured we arrived safely.
In the end - I think what happened was an issue with the air bag solenoid controller. In reflection of the issues (the sudden drop of the passenger side), I realized afterwards that I *never* heard a bang or air escaping! It happened so suddenly and in traffic on a single lane road with very little shoulder area that I started thinking the worst and basically panicked.
In the end - we got the GMC back in the air and drove gently to the rally. It’s maintained height in the campsite.
The main thing I decided to change from this point onwards - once I’m at my drive height, I’m closing all my shutoff valves to isolate each bag for my drive! If my four bags had been isolated, this issue couldn’t have happened…
I’ve heard some recommend doing this in the past, but in my 13 years of my ownership - I’ve never done it. But from now on…

I initially drove with the shutoff valves open, until one airline broke at the bag and the coach dropped down with a bang on I-95 after midnight. I thought I'd had a tire blowout. Lucked out - shut the valve, pumped up the bag and drove off.
Admit it - you're going to enjoy the rally more because you had a successful conclusion to your adventure. Been there, done that, thank you GMC Community guardian angels for talking people off of the ledge.
