2016 Colorado 2WD CrewCab shorty 3.6L V6 3.42 axle
GCWR 12,700 = 7,000 tow rating when wet and loaded truck weighs 5,700
GVWR 5,800 = miniscule payload capacity
Diesel engine available for a lot more money raises tow rating to 7,700 and GVWR to 6,200. I can't find payload capacity, but it's probably still miniscule.
Given GM's history of bankruptcy and less reliability, I would order the Taco V6 with V6 towing pkg.
My 84-year-old Sweetheart would veto the T@b camper, primarily because of lack of a real bed. When we were shopping for a new small trailer, she insisted on:
--- Walk-around queen-size bed, so she doesn't have to crawl around on the bed to make it up, and we can replace the cheap standard mattress with a quality EuroTop mattress.
--- Bathroom with separate shower so she doesn't have to sit on the pottie to bathe.
--- Roomy closet that will hold two weeks worth of clothes for long trips. Small wardrobes won't do.
--- Normal self-contained features such as hot water, AC, refrigerator, cooktop, oven.
We settled on the Skyline Nomad Joey 196S, which was discontinued recently. Replacement is the Nomad Dart 188RB,which is very similar but without our roomy closet off the bathroom. If you can get by with the "Double wardrobes in bedroom", then that one might be the one for you.
