I'd pass on that truck.
Original owner doesn't even have enough on the ball to replace the coolant reservoir cap. What else did he neglect?
Driver seat is squooshed, you'll want to replace that just as soon as you get in/out of it a few times, dragging your hip into the recline lever.
$6400? I don't THINK so. They'll be lucky to get $4500, IMO. If you're really bidding, I wouldn't go over $3k, considering your location.
Probably needs LBJ's and shocks, just from age and mileage, has the crappy steel wheels, vinyl floor, crank windows, no rear slider, PVH Hubs, etc. There's nothing special about it, other than the low miles and ONE neglectful owner.
