Question about propane water heater?

At night the noise of the WH can disturb other campers, particularly if your neighbors are tenting or in a pop-up. Switching it over to electric would maintain HW, but we usually turn it off completely at night because it doesn't take very long to heat up again. It usually is pretty warn still in the morning anyway. Of course I wouldn't turn my LP furnace off in cold weather so 6 of 1 and 1/2 dozen the other.
