2000 f250 crew cab 7.3

I still own a 99 and a 02 F250 7.3 and they are the best PU's I've ever owned. Both have the ZF 6 spd manual tranny so unlike those with a auto... no tranny problems. The front end ball joints seem to last about 100K miles and need to be put in using a torque wrench. I sometimes gross over 26K lbs so no problem with that small of a trailer. F250's could be ordered with a slide in camper package that gave it F350 rear springs (a extra helper spring) and sway bars on both axles but not needed for that small a 5er. If it's been chipped then find out what has been done to the auto tranny.
There's many reasons why a 7.3 will cost you more than a newer 6.0.
