The Z-van was originally available in a 40â length; 45â was offered later. Many of the 40â trailers were subsequently extended to 45â. Refrigeration equipment was available, as well as different landing gear and door rod configurations. Construction began with the ribbed-side versions, then proceeded to beaded-side construction, with the smooth side version representing the most modern construction method.
