Pulling Travel Trailer in Colorado with Tahoe

I agree with Thom above. All these people saying it won’t be a problem, yeah, here’s some real world experience. We did this similar trek this past summer with our 2011 Avalanche (7,900lb tow rating) and 25’ Jayco - gross 5,500lbs. The Av was working pretty good. Pulling over Monarch Pass we were doing 35-40 max and transmission temps hit 245 near the top. Engine temps were up as well which is unusual for the Av. Vail Pass was similar coming from the west. The problem is timing to pass semis that are crawling. If you don’t time it right you risk having to slow until you can pull out and then you have no momentum. Thus ensues the chugging at 25.

You’ll make it, but it will be slow. Right lane, hazards on.
