My grandfather owned several mid-1930's Chevy and Ford big trucks, which he used for delivering ice and coal, pulling trailer loads of beer from Milwaukee and St. Louis to Nashville, and at least one dump truck used to haul gravel for building the runway for an Air Force base in Smyrna Tennessee. The 1934 model trailer-towing rigs had crash box 4 speed transmissions and vacuum-boosted mechanical brakes on the tractors, and no brakes at all on the trailers!
