Dad has a 2002 F350. Loves it. Approx 100k on it, most of the time carrying a Lance camper. Numerous trips over the Rockys. He loves the truck.
A selonoid in the transmission went out the past fall leading to rough shifting out of park. Since it involves dropping the transmission, he did a rebuild while it was out. Probably not needed. Otherwise, no major issues. Engine pulls like a train. He claims it runs better than when it was new.
