The regulator is built into this grill; it's the thingy that the propane cylinders screw into when you use the portable cylinders. I'm not sure how easy it would be to rig up a safe quick-connect. It appears to me that it should be possible as presumably the orifices and such are not in the same unit as the regulator (since it has separate control knobs for each burner but a single regulator), but it's not at all clear from the manual what sort of fittings and connections are used to attach everything together nor other details of the internal construction.
If your RV quick connect is high pressure (on the tank side of the regulator), all you need is a hose or something that attaches to the grill regulator where the propane cylinder usually attaches. In that case, you'd leave the grill regulator as-is.
