My question for the MN guys is what efficiency loss do you see in the cold weather? Just in high 30s in central Illinois now and I'm down 15 percent (at least). I've got 49,000 miles on this going into my 2nd winter, and I would not buy an R1T if I lived any further north. Needs a heat pump bad. Supposedly the new DM in the oil bath dies better, but I haven't heard any real world numbers.
