I have not had a test tow. I can't imagine anyone would care to accomodate a test tow. Either way, I do not own a trailer yet. The reality though is I have no interest is driving anything larger than this vehicle. There do not seem to be too many 6.0L out there, even at the dealers. They just don't order them, at least around here. I'm sure a 2500 with a diesel would be a great TV, but just does not meet my other needs. We shall see.

Engine size is not the problem, it's the ability of the frame/suspension and braking systems to handle the massive load. Just take it easy and slow and you should be okay.

great looking truck... how do you like it?
