From first glance, i'd guess the truck has had some body work, on the fenders.. that knocks it out of the "bone stock/unmolested" catagory.
It's a 3/4 ton, which sells better than the 1.5 or 2 tons, but not as well as the 1/2 tons.
It's a 3 window, which I personally prefer, but the 5 window cabs tend to be hotter sellers in that body style.
The original paperwork is cool, but not in display condition for show purposes.. I don't know that it would add any appreciable amount to the value of the truck.
In my neck of the woods, a truck like that in that condition would sell for between $600 and $1,000. Other markets were those trucks are hard to find (costal and high road salt areas) it would fetch more, but buyers often consider shipping costs when calculating the most they'd pay.
For instance, a truck like that in Indiana or Ohio might be worth $2500 or more.. but if they have to pay $1200 to get it shipped from Ontario to their driveway, they likely wouldn't pay more than $1300.
