Sleeper

A part of the cab or an attachment to a semi-truck often used for loads that travel a far distance. The sleeper contains one or two beds that are of decent comfort (in my opinion) especially with blankets. For two-person trucks, there is usually a bunk bed so that you and your passenger can sleep.

Driver: "We only have an hour left, we need to go to the sleeper"
Passenger: "Ok."
