I spent the last week out in Oregon with my family. While I was there i was able to spend time with my father-in-law and show him the pics of the Bison and what I had collected together to reproduce some of the rigs he used to drive. We spent lots of time looking at images of CF trucks and this is the type of truck he drove.
He told me that the solid green truck was used for in town deliveries, while the white trucks were the road trucks. He also mentioned that CF had canvas topped trailers with hinged walls that folded flat along the side of the trailer and you pulled them out across the width of the trailer to section off the load as needed. So now I need to do more research and look for pics of these canvas topped trailers.
I also needed to know if the tractor is available in the aftermarket. and what chassis would be a good one to start with. I know I purchased a resin body a few years ago, but now am not sure its the correct one. So off I go to find it.
EDIT : Nope, I purchased the International, which is the wrong tractor
