I'll just keep having a conversation with myself! But seriously, I thought if the info was here, it might help someone make the decision whether or not to go this route. It was tough finding guys who had installed Espars when I was doing my initial research. So, further observations now that we have seen some cold weather.

At -30C, I had to take off to pick something up in town. I ran the Espar for 10 minutes and then tried the truck. The truck started with a little bit of chugging but no problems, the temp gauge was up to about 1/4 way. I let it run with the hand throttle at 1500 RPM for another 5 minutes and left for town. The temp was all the way up by then.

Something I noticed: you are supposed to be able to run the Espar and gain more heat WHILE driving. If anything, the interior heater tends to blow cooler once I start the Espar up while driving. I wonder why?
