| The XM523 series was the result of a requirement during the 1970s for a new heavy equipment transporter. Unusually the first two vehicles were built by Kenworth with
International Harvester proving the third. Due to use of commercial components the vehicles were rather high and, eventually none of them were accepted for service.
