Kenn is right - most propane grills are designed for higher pressure.

FURTHER you should have an excess flow (POL?) shut off regulator at the main supply, most RV's include the excess flow POL regulator in the form of a 2 stage regulator at the tank/supply (i believe this is required by law).

I removed the regulator from my outdoor grill & converted (via QD fittings & brass plumbing) our outdoor grill to run off the coach supply (instead of expensive & short life green bottles), by tapping into the existing (black pipe) plumbing under my coach…you can't beat the convenience…HOWEVER….the flow or pressure is a bit low for me…just takes a little longer to heat up & cook (i tolerate it, but wish the grill got hotter, faster).

I did a fair amount of testing (off coach) & determined the pressure straight off an LP Tank was too great & would need regulation. I wasn't willing to run a sep line from the coach tank just for the grill.
