I wish I could go back and edit old posts in this thread, but that doesn't seem possible. So, here's an update from my perspective. Earlier in this thread I described how I'd suffered the failure of a 9336 rear bag in December, only 8k miles after having new bags installed in March 2021, and had received a new 9336 under warranty. Well, I had another 9336 bag failure just a few days ago. Believe me, I wasn't pleased to have another roadside breakdown, particularly due to a rear air bag failure, less than 4 months after my prior event!
To make a long story short, I've followed TR4 and Gatesway in installing 8184s for my rear bags. They seem far more robust and their full metal cone and bottom is obviously what we need. My original installer, Olstrom Custom Coach in Tucson, tells me that in the event 8184s cannot be obtained then 9336s can be used as long as a supplemental metal plate supporting all of the cone is installed under each bag. I think other folks have said something similar in this thread. I'd like to add kudos for Eric Olstrom, who supported and assisted me remotely and worked with me to make me reasonably whole on my prior purchase of the 9336s.
Everyone seems to agree that 7667 bags are still correct for my coach and mine have been fine since being installed in March 2021. However, I will be having full metal plates added under the 7667 cones, since Country Coach only provided a relatively narrow bar that doesn't contact all portions of each cone -- full support is obviously needed for plastic cones and my own experience bears that out.
I hope my air bag issues will soon be a distant memory and I won't have to think about them again for another 10 years or so
