We've found that adding supplemental, portable heat to our RVs adds greatly to our cool and cold weather comfort. Our first trekking experience was in an all-electric Class B RV. It had all the whiz-bang stuff including solar panels and lots of batteries. That fall camping experience taught us the limitations of 30A of electricity and the limitations of relying solely upon electrical appliances.
We do camp during 3-1/2 seasons of the year. Our lowest overnight temperature experience was about 5F, with other nights as low as 20-35F.

We've found methods to supplement the built-in heat sources in our RVs and create a more pleasant experience. I should add that having a backup heat source is helpful in cold weather. In the Roadtrek we could run the engine in an emergency, but I won't do that to heat the coach in cold weather.

One thing to bear in mind is that these RVs have little insulation and a lot of glass area. Glass has an insulating, or R-value of just about zero. Single pane glass keeps the elements out, but that's about all. There are exceptions, but we don't have double pane windows and the Roadtrek 210P has very little insulation. Because of this our RVs can get quite cold when the outside temperature is below freezing. We selectively use Reflectix on the windows and floor carpets as aids, especially in the Roadtrek. We also use an electric blanket.

At the 5th wheel in AZ we have a built-in heat pump and propane furnace. We use the heat pump for temperatures down to 40F and then switch to propane. Winter nighttime temperatures can be as low as 25F at the extreme. A few nights in January the low is 35F. However, early cold snaps can occur as did in December 2022 with nighttime lows of about 35. With full sun daytime temperatures peak at about 65F-75F.

We added a 20 inch x 60 inch heating pad to the Roadtrek. This covers the floor area in the center space. I initially set it up in the 5th wheel, and when we are there, we use it in the living space. It is 120V, 300W and because the surface temperature can reach 125F. I added a control to reduce the surface temperature. G really like it.
