Truck sleepers are compartments attached to rig trucks that vary in size and can be outfitted with beds, a bathroom and a kitchen area. A basic truck sleeper has enough space for a trucker to rest or sleep in during long travel times for deliveries.
As of 2014, truck models can come pre-built with a sleeper unit built in. Kenworth, a truck manufacturer, offers a studio sleeper model that comes equipped with a partially-equipped kitchen. With appliances like microwaves and refrigerators, a truck driver can save money by cooking his own meals rather than purchasing food while on the road.
