Ive had a 02' QC 1500 5.9L for a while and am upgrading to an 03' QC 3500 DRW CTD w/ 6-speedanything i should know? just wanna make sure there werent massive problems with this certain setup or anything haha, also let me know anything good about this type of truck too, id like to hear about it a little before i get it.

 

Well for starters, the transmission in those trucks is no longer in production soo parts are hard to come by. With good care though, they'll last forever. They were having problems with the lift pumps on them, lost of people were putting aftermarket pump on them. Everyone has been complaining about a/c problems and I think the fix was to add a couple of pusher fans infront of the a/c condensor.
