I did not like the idea of installing compressor with electric stuff under the truck bed and having equipment trailer, wanted the compressor to be portable for tire inflation.
So I install the Firestone dual bag controller on the floor next to driver seat and put tire shrader valve on supply end.
Compressor was sitting on the floor behind the seat and I could connect it to the valve while plug-in to cigarette lighter 12V.
I never need to inflate bags on the fly, so never used the option, but adding some psi in the morning was very easy.
The only issue I had to watch was restarting the compressor under high pressure, what would burn the lighter socket fuse.
Had to disconnect the chuck, start the compressor and then hook it up for pumping.
BTW we do have electric compressor in our Mercedes with air suspension.
Those compressors are expensive new, but you can buy used pretty cheap and rebuild kits sell for $17.
The compressor has build-in drier and hose with a filter. They operate at 160 psi easy and last for years.
Would I need another pump for truck, that is what I would look for.
The same Bosch compressors are used by Audi, VW, Land Rover and more, so lot of suppliers.
