Not an a-body but your opinion on worth...

Hey guys, posted this on the truck forum, but zero input, so I thought i would see if i could get a little input here. Ran across a 1985 dodge pickup, 4x4 318 with the factory wheels on it. Royal SE. With the Prospector Package. one owner. I know just looking at a few picks would be hard to tell, but what are these selling for in your neck of the woods in this shape?
Body is very close to rust free, yellow in color and in damn nice shape. would like some opinions on what you guys think this truck is worth 116,000 miles and I think valve stem seals are history. Smokes like crazy. guy is asking 2500 firm... I know that the 85 is the first year for the shift on the fly, and it appears that the common rust above the windshield is just starting. Anything that I should know about this year or body? problems? My gut tell me this truck is worth the asking price, but.... Thanks for your input.......
