@kdfrawg There's a soil & garden supply company not far away that still runs 6 1950s & 1960s Chev tipper trucks in amongst their more modern gear. The reason is simple: modern small trucks are forward control/cabover jobs and can be too tall for some demolition sites. The Chevs are at least 2 feet lower in height and are quite popular with such site managers. Often they'll request the Chevs for that reason.
