ArcticTraveller- I'm going to ask around and see if I can find items to measure the temp on mine- just got back from a road trip to Maine- didn't use the heater for any long periods but monitored the exhaust and felt like it didn't get overly hot- curious to get some comparisons! So far so good with running it- heats the van up quickly and once up and running drawings around 2.8amps- not bad!
