How cool is this? It’s a 1958 Dodge W300M Power Wagon with a swivel frame to accommodate variations in terrain. The Power Wagon was based on the Army’s 3/4-ton truck chassis and was first offered after the war in 1946. The swivel frame was an aftermarket modification done at the time by Willock, a Canadian Company. This unique piece of 4×4 history is currently for sale for $20k.
