I'm assuming you at per using it with a 20 lb propane tank, right? If so, how long does the tank last? Also assuming that you would also be using the tank for cooking as well.I can vouch for the Propex. Works great in an Eezi-Awn Globetrotter. IMHO, the thermostat is a necessity. The thermostat keeps the tent at the right temperature without wasting fuel. (i.e. opening a tent flap to releasel the precious warm air you just paid to heat.) I also like the fact that the Propex allows you to return air from the tent to the heater. This uses less fuel by reheating the warmer air from your tent and also helps take the humidity out of the tent. Just my $0.02
I love my Webasto heater and use it daily. Unfortunately I was nearly left stranded after letting it run all night and the voltage regulator didn't do its job. I will be sure to add a third battery with an isolator strictly for accessories before I depend on it again
it wont run all night since its on a timer. i would warm up the bed/sheets before bed. reset timer just before going to bed and hope it should be enough to keep me warm and asleep the rest of the night. i always carry a jump pack so running the battery dead wont be an issueYou would need a lot more than 2 regular-sized batteries to run an electric heater all night. The dinky little electric heater above pulls 13 amps according to the instructional manual.
You'll be glad when you get it. I bought mine from MVBEGGS, worth every penny. I was just spinning tales of our trip across the El Camino del Diablo in January. At night the temps dipped below freezing. No lie, second night I woke up sweating (sleeping in boxers with a sheet) and my digital thermometer read 122 degrees in the tent.The Propex uses a surprisingly low amount of propane, I borrowed one from a good friend, and used it for 2 nights in Death Valley in January, had the heater on all night, but with the thermostat, it doesn't run the burner all night. I have a fiberglass propane tank and the usage was barely visible.
I'm saving up for a Propex.
