old thread i know but there is a lot of good info on here for people looking to buy a good towing suv. Just clocked in about 600 miles of towing on the same trip that broke my denali. It was a night and day difference. Even with oversize tires 2x too big and a full fresh water tank (30 gallons and another 30 in the other tanks) 15-20mph head wind, it pulled great. There were zero complaints on the truck. I love that i can stay in 4th gear most of the time with the rpm's under 2k. Heck I even used cruise control when I got in the smaller hills. Hardest part was keeping it under 75mph because thats what the tires are rated for. I love this truck so far. Best decision i ever made for our family.
