Heating a trailer while under tow

[swimmer_spe]

I may moving during the winter. It will be a 4 day drive with my trailer up here in Canada. I plan to put my house plants in the trailer.

What is a safe way to heat the trailer above freezing for the 4 day journey.

How dangerous would having the furnace on be? Other ideas?

What about a 12 volt space heater? Something big enough to keep the inside warmer than freezing, but not so large as to risk running down your house battery faster than your vehicle could keep it charged. No open flame, and you could set it pointing at the plants. Just make sure to secure it while you're going own the road, obviously.

No concern there, mine doesn't have any.

I aways ran the furnace in my previous TT while on the road. Not a problem. As long as any slides don't cover furnace vents.

some of the house plants are over 4 feet tall.

If the houseplants aren't too big, you could put them in an ice chest with a couple bottles of hot water.

I have moved my TT many times in the winter months. I am fulltiming in Calgary in it right now. I run all over the place for my work and usually drag it with me.
Although I do hesitate about running the furnace while driving, I have done it a number of times. When the temperature is down around 0F, I can't run the risk of a total freezup while driving.
I have never had a problem doing this but have to admit I am a little apprehensive about it.

Worst thing that ever happened was a full pound of butter slid off my counter top and landed neatly on its side on a heat register. Quite a mess when it all melted and ran into my heat duct....
I still get this weird urge for popcorn sometimes when I run the furnace for a long time....

Not endorsing running with the furnace on but I have done it many times without any incident aside from the butter trip.
