OK I have driven the 5.4 3 valve with a 6 speed. It was pretty nice. But I would still prefer a diesel. I think it is a matter of personal preference. I do tow my camper (10,000lbs) alot in the summer and I think a diesel is better suited for the job I would just like to tow it with an SUV.

Ford needs to get with the program. Chevy just announced they are going to put a smaller 300hp Dura Max in the Suburban this year.
