What should be my expectations with a propex hs2000 for heating a van that's been left out in -10F/-25C temps for the day? How long would it take for that space to heat up enough to take the down jacket off?
Even when it's fully insulated? I'm thinking of using the van in winter in the Canadian Rockies going skiing or something. Do most people just keep it running with the thermostat? Not sure I trust it enough to run when I'm not there.
