Speaking of Conestoga wagons, <em>Four Wheeler</em> magazine is no stranger to the history of 4WD vehicles, and one of the first production 4x4s was the FWD B, like this model B-1719. These trucks were used by the U.S. and British during WWI and had two solid axles and a suspension frighteningly similar to some 4x4s built up until the late ’90s. Why? Because solid axles on leaf-sprung suspension is simple and the system works well. If it ain’t broke, don’t fix it.
