Going back to my prior coach (Forest River Class C) and not my current Challenger:

Furnace, try to get the owners manual for the specific furnace and Thermostat. On my prior coach the issue was not with the furnace but rather with the AC unit and the model of electronic thermostat used. For the furnace to warm the coach the thermostat fan switch had to be set to "Auto". Having the fan switch set to anything else caused the furnace to blow cold air through the AC vents rather than warm air through the furnace vents. This functionality was not listed in any documentation from the manufacturer and was learned through the Forest River forums and it turns out, for some reason, the system functioned as designed.

Hot water, my Challenger water heater (6 gal) is gas and electric and the owners manual provides the hot water rates for using gas, electric, or gas/electric functions. Again, prior coach and I have not verified this on the Challenger, there was a small rocker switch hidden behind the LP lines at the water heater that had to be set to "On" for the electric element to function.

Right now I am de-winterizing and system checking this new coach and have not yet checked the electric side of the water heater. After verifying the gas side works well I turned it off and today or this evening I will switch over to electric and verify that side is working.
