Good discussion here on air bags. I have the Air Lift bags on my F450. I didn't install them - Classy Chassis did.
I have the wireless control system and compressor. I really like the ability to add air or dump air at the touch of an in-cab controller. While my controller is wireless, I'd be just as happy with non-wireless system that had an in-cab gauge and air/dump switch. The in-cab gauge/switch I believe require running an air line and more wires into the cab whereas the wireless control system is just that - a wireless controller I clip to the visor that's a little thicker than a garage door opener.
I can however, see the benefit of "keeping it simple" by having only a manual fill, no compressor and no wireless controller, wiring etc.
Just yesterday, I replaced the "manifold" for my Air Lift sytem. I bought a refurb from Air Lift. The refurb was still expensive ($162 delivered). Once I replaced the manifold, I had to pair (join) the wireless controller to it.

If anyone's curious as to the install process for the Air Lift "Gen 3 Kit 72000" or wants to look at the quality of the docs -
here's a link.
