We do when it’s cold. I prefer a space heater on low to the normal furnace unless it’s balls ass cold and there’s a concern about tanks freezing. Usually just stick that sucker on the kitchen counter and it’ll heat our 28 foot TT no problem.
Just gotta be mindful of how many amps it uses
Just like anywhere. Use it with caution, keep it 3 feet away from anything that could catch fire.
We plug in a small oscillating one into the microwave outlet, works great heats our 31′ motor home.
I use a space heater. It works fine. Get one with an efficient fan — larger fan is better. The smallest size heaters have tiny, loud fans that don’t move much air.
Also if you have pets or long hair or lots of dust (we have all three) then avoid ceramic heaters — on ours the ceramic heat block kept getting blocked by a mat of felted dog-hair like a dryer lint trap and we had to disassemble and clean the innards several times before replacing with a more open design.
I survived -40 in my fifth wheel last winter using a combination of space heaters and the furnace. Took a little adjusting to get all the thermostats kinda synced up but it worked well. I’d have never made it without the extra heat.
If you’re having trouble with tripping breakers you can buy an appropriately sized extension cord and run it through a slide or window out to the shore power if there’s a 20amp outlet on the pole. Just make sure the cord is heavy duty enough to carry the amp load of whatever heater you use.
Temp dropped a couple more degrees after I took this but you can see -38 outside and 70 inside the trailer and 72 in the underbelly storage.

A Pelonis ceramic honeycomb is a really efficient and safe unit.
We camp in the low teens in our 32′ tt. We don’t use the water in the winter though. We’ve got two Vornado brand space heaters that you set the desired temp and they use their internal magic to hear the space evenly and efficiently. Our electric runs about 4 dollars a day at the coolest times.
