Agree a bit on the over heating issue. There is at least one hill about 7 miles long, I think. I can cruise up it at around 55 or so. However, semis must (I think) stay on the right lane. And if you don't manage to get to the left lane because of heavy traffic, you are stuck and going about 25 mph. My truck pretty much can't gain the speed up enough to get back into the left lane at that point. During the summer, I have turned off my A/C for a few miles to keep things cool.
