Ellsworth, once you added year and model it helps to know what you have. From 2006 to now Montana’s have changed a lot. Yours definitely doesn’t have the heating pads or the heat pump. You also don’t have many of the other features of the new Montana’s. You may want to add your unit information to a signature at the bottom (see mine below). There are instructions in the sections above to do that.

Now that I know you have a 2006, your unit has the lines run close to the Frame, so they are prone to freezing in cold weather. You still have some heat in the basement, but not to the level of the newer Montana’s. You have a dual powered water heater - electric and/or propane. Your switch on the tank monitor is the propane operation. There is also a rocker switch in your water heater panel outside that needs to be on to use electric. Hope this helps.
