So for $4000 I would say that isn't a bad deal for that truck. My only issue is the 4.7 does have its issues, the main one having the heads warp due to overheating. I'd keep up with the coolant changes, as that would be something I'd flush as soon as I purchase the vehicle. Mileage wise, its around that time for some expensive parts to go out. Alternator, water pump, the starter and catalytic converters start to fail around that time. Now granted, those parts are not guaranteed to fail at a specific mileage, but they do not last forever. Changing the oil, transmission fluid (if its the old Chrysler made transmission, if its the 8 spd ZF one, then thats another thread topic), coolant flush, diff fluid change, etc. is not a bad idea either, and gives you a chance to see how well maintained the vehicle really was. So for my opinion, for $4000 I would not mind purchasing it as a second beater, but as an only vehicle I would be mindful of it leaving me stranded somewhere due to unforeseen circumstances. If you can talk down the price some more, even better. Hopefully this helps you with your decision, and good luck with your Ram in the future if you do decide to purchase it.
