In North America the term truck camper and its derived acronym TC, are generally used to refer to any recreational vehicle or RV that may be carried in the bed of a pickup truck. In North America, this RV type is sometimes known as a slide-in or cab-over.
In English-speaking Europe the term demountable or dismountable is more frequently used, and in Australia, the term slide-on is used to describe RVs of this type.
Technically speaking, any RV that can be easily dismounted from its carrying vehicle qualifies as a truck camper. In Australia it is very common to see them mounted on flatbed trucks, or even on what, in North America, would be considered a car.
The lines of definition can blur between a truck camper and a recreational vehicle with some expedition vehicles like the xpcamper[3] or the Earthroamer.
