Allstate 1st Gen – CrossCountry: A single wheel trailer appeared in the Sears 1939 Spring catalog, evidently its debut there. This model was called the “Cross Country,” a brand name it shared with a two-wheel trailer shown on the same page. It appears to have been in production only a year and a half. The catalog described it as having “Live Rubber Spring” suspension, touted as being longer lasting than metal coil springs. Its tongue arrangement was totally different from all later models, being straight pieces of metal sticking out of the front of the chassis and connected to the bumper by means of ball-and-socket couplings. (Extension arms could be bought if you needed more clearance between the car and the trailer.) The trailer, rated at 750 pounds of cargo capacity, sold for $36.95. It was made in Niles, Ohio unlike the “Cross Country” two-wheeled trailer which was made in Connorsville, Indiana. They appear to be identical to the “Yocar” trailer made by the Youngstown Steel Car Corporation in Niles, Ohio, sharing the same frames and the same caster assembly with a rubber mount used as a coil spring would be. My conclusion is that that it was this company which supplied Sears with their first single-wheel trailers. The chassis can be described as having a “Y within a Square” frame, with one brace connecting the arms of the Y and two more supporting the base of the Y at the point where the caster wheel assembly connects. The body is formed of wood panels within a steel frame, with a removable tailgate. It measured 54″ long, 42″ wide, and 11″ high, including flare boards. The trailer could also be purchased without the box for $33.50. The same trailer appeared in the Fall 1939 and Spring 1940 catalogs.
