The 1961 Spring-Summer catalog marked the beginning of a new era with the introduction of a leaf spring wheel assembly for trailers. Although this particular trailer was only featured in that one catalog, it stands out with unique characteristics not seen in other Sears trailers of the time. Unlike most Sears trailers, which were typically built in Chicago, this model was produced in a factory near Des Moines, Iowa. The inclusion of the leaf spring in this design hinted at future trends in trailer suspension.
This trailer has several distinctive features, including a curved leaf suspension, a hydraulic shock absorber, and front mounting arms that curve downward at an angle. These elements set it apart from its predecessors. The body design carried over some aspects from the earlier wood box trailer, including a dark blue color scheme and the iconic “ALLSTATE” U.S. map logo prominently displayed on the front. It also appears to have removable front and possibly rear panels, similar to the earlier Wood Box trailers.
While it may have been short-lived in Sears’ lineup, this trailer from the 1961 catalog remains a fascinating piece of history, showcasing innovative design choices and a glimpse into the evolution of wheel assembly technology.
