i asked about that when i picked my coach up and was told that it was pre-regulated. in other words, you would need a smaller regulator for the grill. i thought it was BS but then i noticed a smaller regulator under the stove and a regulator-looking device on the back of the fridge.
so i would assume since each device probably needs a different pressure, theirs a master regulator on the tank and each device has it's own so it operates as designed. (i would also assume the fridge uses less than the water heater, or stove, for example)
