Air bag tire pressure

[newfiepet]

We have a 2006 National Surfside that has air bags behind the rear tires. There are none on the front ones. Can someone please tell me how much air pressure we should have in them? Thanks!

Are there any markings on them ? Maybe you air them up until rear is level with the front end.

If they are like the ones that I had on my suburban or my Excursion, they only hold 10-15 pounds and youeed to bleed it in slow. They're not usually used for leveling,per se, but to beef up the rear suspension when towing or carrying a heavy load in the rear of your rig.
I didn't see where you live, but if out west, take it to your nearby Les Schwab dealer and ask them to check the manfucturer.

There's nothing we can see marked on them. We tested the air and it's currently 40 and 45 psi in them. We're located in Newfoundland Canada. Wondering if anyone out there with similar RV have done with theirs.

I installed Airlift air bags on my 99 Dolphin. Started with 70 PSI made the ride to harsh. I maintain 50 PSI in them ride is good at that PSI. You can experiment with the pressure to find the pressure you like.
