I had a 2017 Colorado z71 4x4 CCSB. 40,000 miles. Averaged 21.6I towed a 6500# camper (7000 loaded) for several thousand miles. I work 4 miles from home. I go to church 35 miles away and it's 20 miles to the nearest Lowes/Home Depot. It would regen once every fill-up 4-5 hundred miles. Bone stock except for front level kit. I would REGULARLY get 30mpg driving 60 MPH on country back roads and 28 running 70. Only 1 time did the "keep driving" indicator come on. Yes, I got the low power indicator that same day. My dealer came by and picked it up while I was at work, did a manual regen for me and dropped it back off before lunch. (obviously I have a GREAT dealership). No problems since. I loved the truck. However, towing a 7000-7500# camper maxes out the Colorado. So, I traded a few weeks ago to the 3.0 Silverado. The power difference is crazy. Turbo lag gone. You'll love either 2.8 or 3.0 Sent from my SM-G973U using Tapatalk
