I had a 94 F350 2x2 dually with 214,000+ on it. Nothing but normal maintenance. Had an 02 for 10 years that I only put 51,000 on. The only issues I had with that truck were alternators. Ford replaced the alternator, with the same POS alternator, 4 times in the first 2 years. Always covered under warranty but a major PITA to get it towed to the dealer plus the downtime that entailed. Bought a high-end aftermarket alternator and never had another problem.

Great motor...pre DEF. If it's a good deal, buy it.
