I bought a 1952 Dodge M37 in April 2008 as my first restoration project. I decided on the M37 because it's appearance, luckily there are lots of NOS (New Old Stock) parts available.
The M37 was produced from 1952 - 1969 and saw service in both Korea and Vietnam, there are 6 variants of the M37:
My M37 has the PTO driven winch which adds 300 lbs to the overall weight of the truck.
