Air Pressure for airlift airbags

You really did not need bags for such a light RV. BUT they can improve ride by starting out with 5psi unloaded then hitch up and check the pressure, it will have increased. Bottom line add just enough air to bring truck back to "LEVEL" and do NOT think you need to make the truck set the same height as without the RV. You want the bags to be there for support and control axle bouncing. If you have not done so throw on a set of Bilstein 4600's.

I am betting with 45psi UNLOADED adding the RV makes for a very rough ride!

Air your tires based on LOAD.
