Those are really great photos and bring back a lot of memories. I was selling dump bodies & trailers in the late 60's and we sold a lot of them in the Carolinas, mainly to State Hwys and also to SC Hwy. Most had pony motors on the front, little Wisconsin THD's. My first tractor was a used White 4000 with a Cummins Super 250 and 10 sp RR so I have a soft spot for them.
Thanks for sharing them.
