One thing I have taken for granted is having on onboard air system so I can change the air pressure of the bags from inside the cab with the flip of a switch. I think it is a must for any airbag installation to be practical. Being able to change on the fly due to changing road conditions is what makes airbags useful.
Perhaps the different experiences with airbags is due to why they were installed in the first place. Some here might be in the camp that they have way more camper then their truck can comfortably handle and require the airbags to "level" out the truck and assist the suspension.
Others (and I think I am in this boat) have just enough or more then enough truck for the camper and don't require the airbags to level the ride height (I have fairly minimal sag with camper) and just use the airbags to improve the ride in varying conditions (higher pressures for winding roads, lower pressures for bumpy roads).
Perhaps that is why there have been such different experiences?
