In North America, the term truck camper and its abbreviation 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 or jack-off is used to describe RVs of this type. In the vast majority of States in the United States truck campers are not registered, titled and are thus not considered a recreational vehicle but rather cargo or a truck accessory.
Long term/full-time residence is sometimes referred to as "Trucklife" in contrast with the more popular "Vanlife" movement.[1][2][3]
