Maybe. They draw quite a bit of current (~8 amps), so you should be
plugged into AC with a battery charger running, or at least have a dual
battery system. The thermostat only controls the temperature of the
outlet air, not the cabin temperature.

You do, of course, want to make sure the whole system is in good
condition and working properly. I'd very strongly recommend a carbon
monoxide detector. Fuel consumption is minimal, a BA6 running on full
is specified to use about 2.5 pints per hour (2.5 gallons/8 hours).

Gasoline is a pretty compact fuel source, containing about 125,000
BTU/gallon. Propane is about 91,500 BTU/gallon (diesel and kerosene are
up around 140,000).
