Hi Guys, it's been years since I posted on here because oh, well, to make a long story short my girlfriend insisted on a fifth wheel which we purchased. The hardware needed for the fifth wheel in my f350 managed to puncture one of my airbags that I had installed when I bought the truck to hold my alpenlite 12 and 1/2 foot Cheyenne. I want to go out on the road again, but I don't want to have the airbag fixed yet. I will have it fixed and probably have the 5th wheel Hardware removed, but for now I just want to get going.

So here's my question. Do I run the risk of damaging anything if I run with the airbags deflated? Is there any other reason not to go out with the airbags deflated?

There are some that have an internal jounce that will prevent airbag damage when running while deflated.
If you do not have internal jounce, the bags could be damaged when the suspension bottoms out onto the collapsed bags.

Most will state that the minimum psi is 5#

I'm on my 4th set of Firestone airbags, I installed new airbags each time I bought a new truck for the last 15 years. I've always run them with zero pressure when I didn't have the truck camper loaded, and never had a problem. But I only keep my trucks for 3-4 years, so I don't know about long term damage.

Just as an aside to that. I bought airlift brand airbags for this issue. Their marketing leads you to believe that their bags can be run flat. HOWEVER, the manual still recommended 5psi, even with the internal jounce guard. I was going to add the wireless one compressor to remedy this, before someone broke in and stole it.

Guys I don't care about the airbags. One of them is already damaged. Eventually I'll get them replaced and have the 5th wheel Hardware removed. I'm wondering if it can damage either the truck or the camper.

Interesting features of the "jounce" tech.

Assuming the rest of your OE suspension is still in place you should be good to go.

That 5th wheel “hardware” did you a favor.

Air bags suck for hauling TC’s.
