he he... those sneaky little bastards tricked me on this one too and left my water heater in by pass when I bought it.
on the left side of the camper, open up the basement pass-thru storage door. You will see your connections / valves on the right hand side. The bypass is directly behind this white connection panel. You need to remove 4 screws (i think it was) to take down the carpeted panel that runs on an angle behind the connection panel. Once its down you will see the 3 bypass valves for the water heater.
