Back in the dark ages, when most pickups only came in regular cabs, a substantial little industry developed around extending them with “sleeper cabs”, so called because they resembled the ones on big rigs. Well, at least I called them that; I don’t know about anyone else. But there’s no doubt that they were once quite common, and a number of companies got in the act.
