Your link didn't work so I couldn't see it but my suggestion will be the same any way.
I'd advise you to get it safe and drive it. After you drive it a while you'll have a better idea of what you want out of a truck. You might decide you like putting around on country roads in an old truck. I sure do. I don't want power brakes, power steering, IFS and all that. Driving the truck takes me back to a different, and I think better, time.
