If you got "fresh maine seafood" in NYC in the 80s it was probably delivered by a 20ft light box truck with those sort of sleeping quarters. All that went away after the DOT decided that sleeping in anything other than a purpose built sleeping quarters could still satisfy the off duty requirements (I forget the exact verbiage). IMO that's how it always should have been, still everyone who made their bucks building those things, and a heck of a lot of motels that catered to commercial drivers, got screwed overnight.
