That thing is a little nuts. Looks like a couple of welders got drunk one night and said, "Hey, wouldn't it be cool..."
Stimpson's Mill (near Forest Grove OR) had a couple when I was in High School. Used 'em to haul crew and tools up into the timber.
Where is it and how much, I want that. I've seen those before on the computer, do a search and they come up, but I've never seen one around here.
They also built those for the forestry service. More than likely thogh if that was built for the railroad it would have a set of track wheels on it too.
Hoooeeee!!! I gots me one o'tham fer huntin'! It can fits two big bucks in the back an one more in tha back seat under the gun rack! That's three bucks boy! Yeeeooo!!
Theres a Yellow and white restored(rodded, who knows) one of the GMCs here in OKC. The guy lives on the north side of OKCand hops onto I35 at the same time I do every so often. Kinda hard to tell much about it at 70mph, but it sure looks nice.
