I see these at truck stops from time to time. The are too expensive for most of the hotshot guys to bother with though. They want north of 10 grand for that thing.
I love this line: "You have direct access to the sleeper berth without exiting the driver compartment."
They market these things to truckers but apparently they haven't seen many. About 2% could or would climb in to that thing from inside a pick up cab.
