Those are Trucks!
Heavy, a bit Clumsy, with "Armstrong" powered controls, these were the real Workhorse vehicles of the day. At one time they were everywhere. I still remember seeing a few of them skulking around local farms and oilfields in the late 1970's. Worn, with tired paint, cracked glass and smoking some, they still pulled their weight.
You really brought back some memories, here! Fantastic builds of some easily overlooked trucks.
Good Show.
