crummy is standard slang for a crew vehicle in the forest industry, prolly used round the world - never heard it here because maybe there's no loggers aboard, or maybe nobody who wants to refer to their beloved ol truck as "crummy"
the burb w/o windows is a panel, tho if it had a single rear door then it'd be a sedan delivery, the car framed version [window-less station wagon]
my 57 panel was a logging camp ambulance in it's first life, and was really the same thing it's forest company owner used for crummies - a panel w/ a bench seat down both sides, room in the middle for the saws and such
