GM 6 liter vortec what are you towing with it?

I have had a few 6.0 Chevy gas trucks. Looked hard at a diesel and in fact passed on the new 6.6 gas until they had a few more miles on them. Stayed with the old tried and true 6.0 and have been happy. I would not go much over 10,000lbs payload but up to that I would not have a problem. You learn with the power curve is for the grades you are climbing and let it go. On the 2019, it gets better mileage and has more power than the '07 so I am very pleased. Life is full of trade offs......
