Propane quick disconect outlet

I am having difficulty finding a propane port (through the side of the trailer). The only one I have been able to find is a Bullfinch (UK) that has fittings not easily US compatible and that I would have to import.
I managed to pick up a SS portable grill from Costco and really do not want to haul around ten + feet of hose to adapt it to the bottle.
