2005, 3500 SRW, 4wd, auto, crew cab, long bed, 192k. I sold my 01. Been looking for a gas truck 3/4 or 1 ton but can’t find a decent used one with crew cab and long bed. My dad has a well used 03 6 spd dually, so I somewhat know the issues with 3rd gens, he has not had many, especially with his maintenance schedule or lack of. Biggest thing I’m worried about is the auto. Appreciate any insight.
