i have the same camper and you have to remove the pannel inside the cabinet next to the front door and you realy have to reach behind the hot water tank to find the 3 valves, note: you wont be able to see the valves you will have to feel for them
its a PITA
wait until you go looking for the water pump
the dealer left the rubber washer out of the suction side of my pump and gave me two days of problems
Great, thanks. I had a casual look, but had not gone as far as to remove the panel yet. I did find the water pump ok though. I took the panel off to change the water filter and it was in there as well.
