Notorious for blowing head gaskets. Definitely do the normal checks(oil stick for milky substance, radiator for the same and all other fluids) I bought a 88 mighty max a few weeks ago and I bought it knowing it had a blown head gasket. Low and behold the individual who done previous head work on it left the valve adjustment screws loose and one found its way under the cam and ruined the head. Luckily I found a donor 87 ram 50 (totaled) but good motor. But in my area they are hit/miss on good used parts(I live in Upstate South Carolina) but I got lucky on mine. A little off point but just be sure to give it a good check over expecally engine compartment area and under the truck for leaks. And like always, go with your gut feelings on it. But these trucks are great lil beaters and when they are well maintained they provide years and many many miles of use. Good luck!
