IMHO if you are looking at a $10k diesel its gonna be early 2000 or late 90's when comparing the dodgeVSford for those years Id have to say the ford has proven to have a very strong 7.3 motor and the tranny is bulletproof, Dodges back then only had a motor everything else on them was garbage! they have only become more superior in the last 5 years over ford. BUT i am also a bit biased so I would say hold out and find a duramax haha good luck!!
