I suspect that you are not too familiar with the 70 series or the 3b. 300000 is nothing for these trucks. Mine had over 510000 and no problems aside from a bad glow plug timer. My 42 had 285000 on it when I sold it. I called the guy back to buy it back from him and he had over 5020000 on it and would not sell because it runs great. Suppose that at 300000 it had only another 100000 left in it. have a look around and see what 10000 can get. It wont get you a 4x4 truck that gets 20+ mpg that requires only minor maintenance to keep running, or a truck that wont bust an axle, tranny, tcase, and so on if treated with respect.
Litespeed,
I wish that I could afford the time to look at the truck for you. I might be able to squeeze in a viewing tonight, but most likely not. You could pm me your number and we could chat. Sometimes chatting on the phone is better than chatting online. On Wed. I leave for Edmonton to complete my Ph. D., and I wont be back until Wed. of next week. You should rethink your notion of value. If you dont think 10000 is too much its not. If you really want the truck get it, but I caution you to not keep looking at other trucks to see what a deal you got. Buy it and be happy. Consider the trucks that Wayne sells. They are indeed nice trucks, but they come at an extreme premium. Have a look at his site. However, he sells them. Some folks would not pay the asking price, but some folks will because they have thier own sense of value.
My thought is if you buy it you will be happy. If you doddle and wait and ponder and it gets sold, you may never find another. Recall that there were about 600 of these ever shipped to Canada. You really should also check with your wife too. I aint claiming to be Dr. Phil here, but it just seems common sense to talk it out with someone you trust enough to want to marry.
Edit: If the truck you are looking at is the one in the Autotrader, be cautious. These guys are nice, but kinda shady. I looked at the hdj81 they have had on thier lot for almost a year, and asked a few questions about thier mechanical inspection and they provided no satisfactory answers. No satisfactory answers were provided about thier warranty either. The truck is still the truck, in that it is still reliable in its own right, but I would not buy it thinking that it has had a mechanical inspection, or a warranty.
