Minimum Features
In order for a converted vehicle to qualify as a motor caravan it must have certain minimum features, as follows:
1. a door that provides access to the living accommodation;
2. a bed, which has a minimum length of 1800mm or 6 feet. This can be converted from seats
used for other purposes during the day but must be permanently fixed within the body of
the vehicle;
3. a water storage tank or container on, or in, the vehicle;
4. a seating and dining area, permanently attached to the vehicle. The table may be
detachable but must have some permanent means of attachment to the vehicle. It is not
good enough to have a loose table;
5. a permanently fixed means of storage, a cupboard, locker or wardrobe;
6. a permanently fixed cooking facility within the vehicle, powered by gas or electricity; and 7. at least one window on the side of the accommodation.
