look for mods. look at the top of the pump see if the cap is missing. if it is then thers a good chance someone has done some mods. when i got mine a old man had it. he was a painter so u can imagine what it looked like. the intioreor was just like new. had a couple of paint spots but thats it. he dident treat the motor bad. he drove it like a old man would . so i gess look at the person u get it from not just the truck.

Check for leaking rear main seal and check the frame for cracks around the steering box take a good long test drive then start checking for leaks
