Does the furnace run ONLY on gas ? And same with the WH ?

If the WH is propane only, our previous owners bought an after market kit for our to add an electric element. You just have to plug it straight into any 15 amp outlet. It work great, and get s just as hot as the gas heat. The only downfall is that it takes longer to heat and re-heat.

When we had an absorption fridge, we defaulted to Auto unless we had low power at a CG. Then we set it to LP.

If your electricity (AC power) is coming from an inverter, you may very well want to use gas as the fridge uses a fair amount of electric energy over time, around 300W for maybe fifteen or twenty hours per day. Frequently an inverter would be installed so as to not power an absorption fridge, but there can be a lot of variation there.

AUTO mode does means use electric if available and gas if there is no electric power.

I run our RV fridge on inverter pass through power, but am careful not to have the inverter on if set on AUTO and unattended for awhile. That way it will switch to gas, with a power loss, rather than deplete the batteries over time. When underway and the genset isn't needed for ac, I run it on the inverter. There's a small elect fridge in the basement as well, but only with drinks and not much of a concern, with however we're doing it.

Wow, the variety of answers here is mind-boggling. Even though they are all essentially the same answer, they all take different routes to get there! Easy answers for "most" RVs are as follows:

Fridge uses either propane or 120VAC, but always needs 12vdc for the control board.

Water Heater uses propane (some can also use 120VAC), but also needs 12vdc for control board.

Furnace uses propane for burner, and 12vdc for blower and control board/thermostat.

Air Conditioner uses 120VAC, but also needs 12vdc for control board/thermostat.

Stove/oven uses propane only.

Microwave uses 120VAC only.

Water pump uses 12vdc only.

Lighting uses 12vdc only.

mine is always on 'gas', thats where i leave it
unless i run out of LP
then i switch to electric

i consider electric mode as a backup option

do most just put the fridge on AUTO ?? And let it switch from gas to electric by itself ? This has AUTO and GAS...no electric

Unless you have AquaHot...

Or the Truma Combi.

Unless you have AquaHot (probably not in a 26 footer tho)

The Winnebago Class B units have a combination gas burner and electric element furnace that you can use when on 30A instead of burning gas. I don't think they offer that in larger models.

I think I saw that at the rally. A euro style furnance that could be electric or gas.
