Your Hot Water heater will run on both electricity and propane but the furnace only operates on gas. On our Cougar, there is a switch located in the exterior HW panel/compartment that has two positions - ON and OFF. The small, black rocker switch is located near the bottom left-hand corner of the tank. It may be in the OFF position so that is why you are not able to heat the tank with electricity. The tank, BTW, will operate on both gas and electricity at the same time.

If you want "furnace" heating, then it's either propane or nothing. You can always use one or two of the small, space-type heaters instead of using the propane furnace.

There is no owner's manual that is specific for your Challenger -- the manual is the same for all of Keystones' RVs.
