So, Michael, you have the 40k BTU model of the Summit heaters, right? I would like to know how hard it blows on its high setting from your prospective. Just mapping out what do do when I get one because I plan on using only two of the three available speeds.... I think.
Chris - lets just say when the truck is warmed up to operating temp, I have never had it off of the low setting! I generally open my wing window to get a mix of cooler air, its so hot. And that is in TN winters getting below 30 degrees pretty regularly.
Yup, 40k
