Thats a good looking truck. I hauled grain out of the midwest when these field trucks caught corn at the turnrow and hauled it to the elevator and spent the rest of the year in a shed. Now semis chase the combine and the bobtails are obsolete. Many of them got moved out of the barn about 30 years ago when they became obsolete. Looks like yours was allowed to stay in the shed. Just about all of them were stretched to accept a longer box. They wee grossly overloaded as to manufacturer's rating, but it didn't hurt them because they didn't go very far and they didn't go very fast.
