Electrically Heating TT Underbelly

Has anyone made or found a way to electrically heat the enclosed underbelly of a travel trailer? We just finished a trip to Ruidoso during which the temperatures were below freezing for much of it, down to single digit one night! Of course I was prepared to and did run the furnace as I have a heated and enclosed underbelly to prevent freezing underneath. We did burn through the propane, which I figured we would, but didn't expect quite as much as we did.

This got me to thinking, if we are hooked up to shore power, about how to heat underneath electrically. I was thinking about maybe some type of compartment heater to heat it separately, or maybe even a small ducted fan to just pull cabin air and send it underneath.

We don't winter camp much, and this was about the first time below freezing, but I just kind of want to be prepared for the next time, or maybe some emergency reason I may need to camp in freezing temps.

Has anyone really experienced water freezing underneath down to 15-20 degrees while camping, which is all we typically encounter in Texas, and has anyone found a good or productive way to heat electrically?
  • My rig came with electric heat pads under the tanks, but I still run the furnace when it gets down into the low 20s, just to be safe. While those heat pads protect the tanks, it's the rest of the plumbing I worry about. I would not feel comfortable with only one type of heat when the temps drop into the teens.
  • I guess you could simply put an electric space heater blowing warm air into your underbelly.
    Have also seen folks put a higher wattage light bulb in the underbelly for enough heat to keep pipes from freezing...or maybe a heat lamp.

    Of course, being very careful and mindful of fire danger.
