In the last 5 years, I have owned a Tundra 5.7, Ford 250 6.2, and now a Ram 3500 CC SB 4X4 with 6.7 cummins.
Obviously, the ram is in another world as far as power goes compared to the gassers. I tow an 8k travel trailer and for towing, I will never own another gas vehicle. Also, this ram is the most refined truck I have owned - granted it is a Laramie trim, but it is a very nice truck. Also, check the resale value on cummins diesel ram trucks - some of the highest in the market.
The tundra was a very nice truck, but the limited Payload is why I gave it up. Never had any problem with pulling power. Gas milage was terrible - average around 13-14.
The Ford was a mistake - I will never own another Ford as long as I live.
