Just throwing this out there for information. I had a denali with the 6.2 to tow the family and TT around for about a year. I hated every minute of it. So many problems with it. Everything is made out of plastic from 07-13. That rig was literally falling apart. I drove 14 hours 1 way to trade it in on a 3/4 ton 8.1 suburban. Night and day difference and I could not be happier with my purchase. I liked the look of the newer 3/4 tons better, and I like the 6.0 with the 6L90, but I knew it came with the same plastic **** as my denali.
