I bought this 2012 Chevy Colorado with the 3.7 liter 5 used with 21,000 miles. I then took it on a 6,000 mile road trip this September 2012 thru 22 states. From Charleston South Carolina, to Great Falls Montana to Parker Arizona back to Charleston. The Last leg of the trip from AZ to SC I towed a 2000 Dodge Dakota single cab with a frame hitch behind my Colorado. throughout the entire trip the truck ran excellent. Before towing the Dodge I averaged 24.5 MPG highway at about 75 MPH. Towing the Dodge I managed 15-19 MPG. driving up the continentual divides in both Arizona and New Mexico I was able to maintain a steady speed of 70 MPH while towing. The truck would run at about 2500 RPM.
Simple to use interior. Basic no frills set up. Very smooth and quiet ride. Great gas mileage for a truck. ran A/C on full while towing and did great
Interior build quality is a bit on the low end. Seats sit low in the truck, Noticable if you are short like me 5ft 8in. Short bed in Crew Cab model.
