I appreciate the responses I got regarding the route from Las Vegas to Reno. It sounds very boring but very doable. But we are now considering taking the I-80 route out west to see parts of the country that we haven't seen before. Our only area of concern for towing is that stretch from Cheyenne to Salt Lake City. Last year when we went out west, we took I-70 to I-15 and got to Salt Lake City that way. We did not like that route at all! We saw two trucks with smoking burned out brakes, and I was a nervous wreck. I would love to see some of Wyoming, but not if I have to go through that kind of experience again. Has anyone done both routes? I would appreciate your opinions as to how I-80 compares to the other interstate through the Rockies.
