Maybe just hold out for a factory solid axle truck? and also factor in a new timing belt right off the bat unless the guy has documentation for it being done recently. If the timing belt goes the 3.0 is toast as it is a interference motor (if the valves stop moving the pistons crash into them) I see toasted 3.0 trucks on my c-list a lot because people don't stay on top of the timing belt. the 3.4 is a non-interference motor so if the belt gos engine is still good. The 3.0 will probably last just fine if you stay on top of it. i might hit him at 2000 or under and unless he has all the maintenance records tell him you gotta put more $ into it just to trust it.
Thank you very much I'm going to look at the truck tomorrow, I really appreciate all the info guys. As always very helpful bunch of people here.
