Firestone Airbags - how much air pressure to keep in them?
I have been using my Firestone Airbags for a couple of years now and have never really asked this question before. I have a 2014 Coachmen Leprechaun 320BH.
So what kind of air pressure do you guys use in them and why? Curious to hear everyone's opinions.
Thanks in advance.

Way back when we had a Class C with air bags, I kept the air pressure at about 80-90 lbs. But we were also towing a trailer that weighed in about 3,000 lbs.
OP, what PSI are you running now?

Unloaded - 10 psi. That's just enough to keep from hitting the overload springs while driving.
Loaded - 50 psi.

I have 55 in them now...I do pull a car behind me - small Civic...55 seems ok when not pulling...I haven't found a comfortable PSI setting when pulling the car which is why I am getting around to asking.

Air bag PSI
I would suspect that pulling a TOAD will not put much of a load on the suspension, as there is little tongue weight. There will be an extra weight being 'pulled' but that should not effect the air PSI needed in the air bags. I would work around the PSI that you use when not towing the TOAD.
