I'm very happy with the MTs on mine. I've got about 10k on 'em and they seem to be wearing very well. They're fairly quiet on the road but my truck is straight piped so noise isn't really an issue.
My brother has the ATs on his 02 dually and he's happy with them as well.
i have the m/t's on my truck. i love them, other than everyone has them. however not many "e" rated tires in 35/16r out there. got about 35000 to 40000 on them with alot of tread left. gotta rotate and balance them alot!!
