Need actual owners experience on which 1 ton to buy.

I have a Ford F-350 with a 7.3 liter diesel. It has been a great truck since buying new. I replaced the brakes at 130k miles. I just had the front end redone at 165k miles, the Dana 60 front axle is extremely strong. I have never aligned the front end or rotated tires but have gotten 65k miles out of the tires, and the truck has always tracked straight. I have towed with it a lot and the trans is fine at 165k miles just by changing the fluid on time.
