Thanks for everyone’s advice. This kind of went the way I thought it might. lol Everyone with a diesel says go with a diesel and everyone who pulls with a gas engine says they work just fine. I went to GM’s website and called them on the phone and they said you can tow a 5th wheel up to 14200 pounds with the 6.0 liter gas engine. After shopping around I’ve found that I can buy a new gas truck for the same amount of money that a 3 year old diesel will cost with 50,000 miles on it. That’s a hard pill to swallow for me anyway. I haven’t made up my mind yet maybe I’ll find a better deal before I buy. Thanks again for the advice.
I've got the 6.0, and it as been great for 225k miles, but I tow 8k lbs. I don't think you will be happy at 10k lbs +. Maybe the new 6.6, or the 6.4, but I think the 7.0 is under powered for that weight.
Mine coming up a 7% grade yesterday, I was at 5000 RPMs, doing 45mph, and that was all she would do pulling 8k lbs.
