we porky says -

there should be one already - under the drivers door, between the tank & the box.
other wise get yourself a glad-hand air line....



i also installed ball valve on the one mounted under the drivers door / cab.
its a bit of a pain to use the coach air to fill up the tires, since the tires require so much pressure.

i keep a CO2 bottle in mow storage bay - w/ an adjust able 175psi regulator on it - it'll fill a tire pretty quick & i don't have to have the coach engine running, the regulator cost me about 55 bucks & i had the tanks (from an old keggerator)....i exchange the tank at my local welding supply story for about 14 bucks when its empty.
