Well it's more based on what drives comfortable for the weight of your rig. I use 70 to 75 psi. Most find anywhere between 60 and 80 works well

x3! When i'm not towing our boat, i'll keep them around 60. When towing i'll bring them up around 75. I installed them myself and they sure helped alot with rear bounce.

Whatever you do, donít go too close to 100 psi. To get in our driveway, we use 85 psi. There is a Firestone Ride Rite website that has the airbag pressure information.

Here is what the manual says about recommended pressures:

STEP 6 ó CHECK THE AIR SYSTEM
As a general rule, the air helper springs will support approximately 50 lbs. of load for each psi of inflation pressure (per pair). For example, 50 psi of inflation pressure will support a load of 2500 lbs. per pair of air helper springs. FOR BEST RIDE use only enough air pressure in the air helper springs to level the vehicle when viewed from the side (front to rear). This amount will vary depending on the load, location of load, condition of existing suspension and personal preference.
www.ride-rite.com

NOTE: Once the air helper springs are installed, it is recommended that the vehicle not be lifted by the frame, as over-extension may occur, resulting in damage to the air helper springs. However, should it become necessary to raise the vehicle by the frame, deflate both air helper springs completely.

NOTE: TO PREVENT POSSIBLE DAMAGE, MAINTAIN A MINIMUM OF 5 P.S.I. IN THE AIR HELPER SPRINGS AT ALL TIMES.
MIN PRESSURE 5 PSI
MAX PRESSURE (LOADED) 100 PSI

Correct me if I'm wrong please. According to these instructions the bags should be deflated when leveling the motor home since the jacks are connected to the frame. Or does the Motorhome have to be lifted completely off the ground to cause possible damage?

That's what I thought as well......designed to break?

You are probably correct. From my experiences I've concluded they sure aren't designed or built to last!

Wow, thanks for the info! I didnít know this at all, and we have used our levelers with our airbags inflated! I hope we didnít damage anything.

L&L,

I don't see how it would be an issue using the levelers with the air bags filled as long as the levelers do not raise the rear wheels off the ground. That is a condition you should try to avoid at all times even without air bags. As for myself, I try to position the RV such that the levelers only have to raise the rear end as little as possible. I think this will reduce stress on both the levelers and air bags as well as providing more stability for the RV. And if I was at a site where the levelers where at their maximum reach, I might just dump the airbags as a precaution. So far that has not happened.....
