Fumblin, The house that I'm talking about is the one on the corner of the county road. If I remember correctly, the road comes down beside the barn I'm talking about, and the pasture is out in front, between the barn and the cnty road.
I've only seen the doors open one time. However, during that one glance, I did see what appeared to be a pretty nice looking AD truck in there. I asked around, but no-one knew what I was talking about, as they'd never seen it either.
I'd be curious to know what it is, if you ever find out.
As for the uncle... I don't know about an AD, but he does have a 1.5 or 2 Ton (red) farm truck he bought at a farm auction. However, it's an early 50's blue oval, rather than a bolt.
