So I'm guessing the water heater is LP only?  The switch next to the door has a cover over where an electric water heater switch would be.  We also ran out of LP in one of the tanks this weekend (with full hookups).  Wouldn't have noticed if it wasn't for the hot water not working.  Once I switched tanks and got the air out of the lines it fired up just fine and we had hot water again.

Z1 is a propane only Atwood heater. Was in 2012 anyways, there was not even an option for electric. Not sure about 2013.
Edit.. just checked, and 2013 is showing an electric heater as an option.

What model do you have BourbanRam? We have 271bh, camped a few times last fall when we got it, hoping for more this year. We are planning a trip to NewBrunswick in August. Tows well, and has a full load of featuresthat we really like. Good bang for the buck!
We have not used a tank yet, using furnace, and propane water every trip.

We just purchased a Z-1 Bunkhouse and brought it out to our seasonal site this weekend. Got everything working fine except for the hot water. We want to set it up using the electrical not gas as we are paying for a full service site and dagnabit we want to get our moneys worth. So here's the problem. We cant find the on switch. Owners manual says its in the panel outside by the back of the camper. Opened it up. No on switch. I should have taken a picture. On another diagram it shows the switch but its not shown within the diagram but just under it. There is a switch just inside of the entrance door for the gas and a slot for the electric but no switch. The specs inside of the cupboard says its gas/electric.
