3.0 = BLOWN HEADGASKETS. There was a recall done for it, and if it has not had the recall done, I would be a little iffy. They tend to blow headgaskets a lot, like ever 20,000 miles (a kid I know has one in his 89 4runner and regrets it all the time). Plus the engine bays are a little cramped, well at least the 2nd gen ones are, I am not too sure on the 3rd gen engine bays.
O ok, ya ill ask him when i call him tomorow.
The truck may have a lot of life, but does the 3.0? Thats the real question. Personally I would just go for the 4 cyl one. 
Ok, well ill ask him a few question about it, and then ill let you know what he says
