Depends what you're towing. My 6.0L 2500HD doesn't work too hard pulling my 1 ton TJ on trailer. Towing my ~8k 30ft camper it works WAY harder. It's either screaming or shifting far too often on the highway, its happy place is 3rd gear about 60mph and single digit MPG pretty much no matter what. I don't like going that slow, especially on the highway. Going to try towing with my wife's 09 5.3 Tahoe this year. I'm hoping the aero advantage and 6 speed work well. Adding helper bags, brake controller, and trans cooler so it's not overtaxing it.
