From what I gather with the pic posted earlier in this thread, these grills appear to be of the Coleman Perfect-Flow Series. Although you can adapt the grill connection with a series of brass fittings and 1/4" Male QD, the R430B565T Regulator that comes with this grill has the gas flow control built into it. If that is eliminated you will have no control over the grill flame. So you would have to plumb-in a flow control valve. For a $70 grill that wouldn't be cost effective. The regulator has to be removed as the RV gas QD is already regulated down to around 5 PSI. You can't have two regulators on the same line. Use expensive small cylinders, carry around an extra, small refillable propane cylinder? Decision is yours.
