Here's what I order on April 7th. It's a loaded ZR2 (not Desert Boss). GM still hasn't accepted the order. The wait is painful, but I'm stoked. I go back and forth owning full size and Colorados. I can't decide which I like best. I know there are strong opinions on this, but I really go back and forth.
I have a 2016 with 11,000 miles. I have found an intermittent problem in which the heat wont come on. Crank up the temp and the fan goes to full but its blowing cold air through the defrost. Even manual mode won't heat the air up. Of course when I go to the dealer it starts working. I want this fixed before winter, but it has to not heating before dealer can diagnose it. Frustrating but I still love this truck.
