A campervan is a self-propelled vehicle that provides both transport and sleeping accommodation. The term mainly describes vans that have been fitted out for use as accommodation. Campervans are considered Class B recreational vehicles or motorhomes because of smaller size and more van-like handling.

A typical campervan is equipped either with a "pop-up" roof which is raised during camping or has a fixed hightop roof.

Campervans usually have a small kitchen with a gas/electric refrigerator and a two-three burner gas hob and grill. They generally have dual-voltage lighting which can work off either a dedicated battery (other than the van battery) known as a leisure battery, or off AC power, supplied at a campsite via a hook-up cable. Larger models may include a water heater, a portable toilet and even a shower.

Class B recreational vehicles are commonly known as Dormobiles or caravanettes in the UK, or as 'Kombis' in Australia and other countries. This trend started in the 1950's after Volkswagen commissioned the Westfalia company to use the Kombi version of their Type 2 transporter as the basis for a campervan.
