Running Furnace While Traveling

I never had a need for heat in the camper when I drive, but thinking premtively, as far as I notice all campers have sliding window right behind the cabin.
Lot of trucks have sliding rear window and if not, you can retrofit.
I heard that tractor inner tube makes pretty good seal between truck window and camper window, this way the enormous amount of engine heat instead of being wasted, will go to keep the camper warm.
You can run the furnace blower occasionally to distribute heat to tanks, but as posted above, that might not be necesary.

Leave the heat on the night before you leave then shut it off and drive. Unless it is really cold it will not freeze. I leave my water in when it gets just below freezing and not a problem. I also leave my taps open so not to build up pressure.

One thing to be concerned of is the tanks and water lines are designed to be heated by the forced hot air. I have supplemented with ac or gas heaters but all that really does is trick the thermostat and then the onboard heat does not heat the tank/basement/waterline areas.

We often run our Furnace while driving when its truly cold and we have the camper un-winterized. Last time we traveled when it was 19 below zero when we left Stanley, a 6 hour trip used almost an entire 20 pound Propane bottle.

GARY

I've do it no problems just be sure to shut off the furnace when refueling.

One thing folks don't think about much is that the fan will draw a lot of juice from the house battery.

In my case, probably because I didn't run a direct charging line from my alternator - the house battery will run down long before I need to worry about propane. If you have a good strong charging current from truck to house battery you will likely be OK but it's something to consider.

X2 on the leaving it winterized. We use pink stuff to flush the toilet when underway and put a gallon of pink stuff into the Black Tank when winterizing.

I've run mine when traveling.

If you are at a place where you have power, I'd plug in an electric heater to warm up the camper at least a day ahead of time, that will save on propane to heat the camper from freezing temps.

What are you still doing in Petoskey? Don't you know that we set record temps up that way? Just joking with you as I know the area. I would leave it winterized and not put any water in it. I have run my heater when traveling.

Been discussed many, many times.
Yes, it's fine.
