Yes, I also had Air Lift 5000 air bags with an on board compressor and in-cab dual gauges with individual air bag controls. I removed the air bags after the driver side air bag support bent from hauling heavy and the pounding they took from rough roads. I still have the compressor, in-cab gauges, controls, and compressor on my truck. I may eventually go back to air bags, but will try PacBrake air bags instead since they appear a bit more robust than Air Lift.
With air bags I would have the convenience of leveling the truck/camper combination side to side while driving in a cross wind and also be able to lower the back of the truck/camper slightly by deflating the bags when parked to aid leveling from front to rear. I never ran over 35-40 psi in the bags. This option isn't possible with Timbrens.
