if you guys don't know much about diesels and still want one go for a 89-93 ram with a cummins they are still 100% mecanical motors ands need nothing more then 1 wire hooked up to the fuel shut off to run the 92 up auto trans ones have some electroics but they are just there to make make the trans work the best part is even if it has 500k on it they still run great or if you don't have much space instead of getting the 5.9 6 cylinder get a 3.9 4 they make almost the same horse power stock and could be found in alot of bread delivery trucks and stuff like that
