Pulling Travel Trailer in Colorado with Tahoe

The weights and measures people will be asking you for more information. Your tow capacity is, standing alone, not worth much. However, I have some experience with that area, having lived there for many years. You might consider other routes to Colorado Springs. Of course it depends on where you are and very you are coming from. But you could go through Breckenridge, up over Hoosier pass which is not bad, and down through Alma and Fairplay, that being on Highway 9, and from Fairplay a couple minutes jaunt on I believe it is 285 over to Highway 24 and East to Colorado Springs. I'd tell you not to be scared off from the Eisenhower Tunnel and Vail Pass. But Figure on losing approximately 3% of your horsepower for every thousand foot gain in elevation. Don't try to keep up with fast traffic, just maintain a comfortable speed for your engine and transmission. Use gears on downgrades where necessary, keeping off the brakes as much as possible. That drive, particularly west of Glenwood Springs on I-70 is just gorgeous. One of the most beautifully yscenic highways in the country.
