Selected Dodge Power Wagon Specifications

  
  
This is a compilation of selected specs for Dodge Power Wagons ranging from the W100 through the W500, including the WM300 Power Wagon. The intent is to provide data representative of the years 1961 through perhaps 1968, pulled from various years of Dodge truck shop and parts manuals, Hollanders, Motors, and other odd manuals and literature, original and otherwise.

I've included specs on the D Series trucks of those years and weight range. This kind of info is invaluable in deciding what can be made to work with what. For instance, you've got a good drive train but the frame and body are shot. Will a D100 frame be as strong as a W200? Will the springs interchange? These specs will answer a lot of those questions.

Also, check out the incredible Fargo Power Wagon brochure, to the right. This baby has the best pictures and descriptions I have ever seen for most of the various implements available from the factory for use on Power Wagons.
