Anyone using Manual Valves for Bags?

[jermasaurus]

Does anyone have an airbag setup that uses manual valves? I wan't to eventually do an airbag setup on my truck, and thought that would be kind of different.
The vavles I have in mind are the ones for air operated lifts. It is a lever type valve that has a source, fill, and dump all in one.
Whenever I finally do this I want to permanantly mount them on/in a center console. Maybe have it dump right through the floor or out the side of the cab.

The only downside that I could think of is that you would have to run air lines through the cab. I want to keep things simple. I appreciate what switches and solenoids can do, but it would somthing different. Anyone done or seen this?
