Welcome to iRV2.

The forced air furnace is propane fired , only .

Your roof air conditioner maybe equipped to act as a heat pump that will provide heated air to ambient temps in the 40s .

If you didn't get manuals for your RV appliances take a look at this site for free operator manuals .

Polar Package is marketing ...insulation values, enclosed/heated under belly, attic venting etc

Furnace is DC powered and propane fired. No heating elements etc
Propane flame heats air via heat exchanger that is circulated thru RV.
In COLD weather furnace heat is needed as it blows warm air into area around the tanks and plumbing lines

If by 'heater' you mean Water Heater vs Furnace...
Yes you can use the electric IF it is a gas/electric water heater

Hi & welcome to iRV2. Glad to have you.

I had a 2004 Cougar 5th wheel so mine is of the same era as yours. It might operate the same. The furnace was propane only. My model did not have electric heat. The only way to have electric heat is to either have heat strips incorporated as part of your AC units or to have actual heat pumps in your AC system. Neither were options for my model & probably not yours.

Does your thermostat look something similar to my photo below? Then you don't have electric heat.

As Old-Biscuit noted, a "polar package" is insulation only. It includes an enclosed underbelly, having heat ducts provide radiant heat to the tanks & extra insulation in the roof. That's it. Mine also had the polar package. It has nothing to do with heating your 5-r, just keeping it warmer when it is heated.

By combining the two answers above you can see "it depends." Regular RV furnaces don't have an electric only option. As mentioned above, in the furnace the propane provides the heat, and 12V runs the blower.

Unless your roof air unit has a heat strip option, or is a heat pump, you won't have an electric only option. This is not uncommon, so what a lot of people do is use portable electric heaters. If you do a search on portable heaters you'll find a ton of opinions on what works best.

The big caveat is what Old Biscuit mentioned, and that's making sure your wet bay has some heat in freezing temps. RV furnaces will send some warm air to the tank area to keep your water from freezing. If you use space heaters this won't happen, so you need some way to keep the water tank and lines from freezing. I use a small, low wattage personal heater I picked up at Walmart. It's important to note that in my case, I have an area I can place this heater where it's safe, and provides heat the the proper place.

If your air conditioner has the heat strip option, be aware they don't produce a lot of heat, so if it's really cold, you may need to supplement. Similar with heat pumps, they only work above a certain ambient temperature.

Of course the all electric options only work if you have utilities.

Is there a reason you don't want to use propane?
