Heating mats

[Fred]

I am looking for the best way to heat my 67 8x16 Aristicrat. A 12vdc low watt 10foot runner seems best but I have no ideas on which ones work well or other options. Any ideas?
Boiling a pot of beans on low works but I now have solar and would rather take advantage of free energy than refuel propane tanks.

Catalytic heater, prolly a 6100, would do well. No moving parts, and easy to install. Avoid the ODS models which will shut off over 4500 feet elevation.

Thank you David. I'll look into those.
