Yeah, I'm considering this myself. Although, you could always mount the Happ panel-top holsters on top of a wood block or plastic enclosure that you bolt into the side of your cab. Or, that's an idea, just get a couple of those black plastic project enclosures from Fry's, the ones with the removable end-panels, uncover one end, then bolt the whole thing to the side and use it as our holster!
