Well, I did some towing today! About 8k, near as I can figure. I could run right along with the valet off, and temps weren't bad. It was hilly back roads, and got up to about 1200* a couple times. (short sharp hills) With the switch on,
it climbed pretty quick, 1400 once. Now I'm curious about how hot it will get with 10k on board, on the highway.
