I had a 2010 CrewMax 5.7 and used it to tow a WindJammer 3065W. It pulled great! I really loved it. I put air bags on it because the springs were weak, although the ride was kind of rough. LOL. I moved to a Ram 3500. We towed roughly 20K miles with it and were really impressed. I loved the 4.30 rear end, and the way it pulled from the light. We pulled to Ouray, CO from Albuquerque a couple of times, and was really impressed overall.
The only disappointments that I had were:
Front brakes were HUGE, but I warped the rotors one day coming down a big hill in Ruidoso, NM. I put Cryo rotors on and all was good.
The springs in the rear were as stiff as my 3500, but didn't have the carrying capacity.
:) Enjoy!
