What is the BRAND/MODEL of your water heater?
Suburban ....SW10DE
M would have the 'motoraid' (
M designates that feature)
Atwood .......GC
H10A-3E would have the 'motoraid' (
H designates that feature)
It is a 1/2" 'U' tube welded to the outside of tank wall in back and has engine coolant lines that go to/from the tube
Hot coolant flows thru while driving....heating water to roughly 130*F over the course of 2 hour drive time.
Don't know model number.....just look at backside of water heater tank and see is coolant lines are connected
