Living in the vehicle, not beside it.Source: Stephen Stewart
Overland vehicles can be divided into three groups depending on what is expected of the vehicle. At one extreme is "transport only". All the vehicle is expected to do is to get you, and your luggage, from A to B (for example travel by car from hostel to hostel). At the other extreme is the "live-in campervan" where the vehicle is expected to provide both transport and the comforts of a "home".
In between these is the "live-beside" vehicle. This is typically a 4x4 (SUV) vehicle (often a Toyota Landcruiser or Land-Rover Defender) with a tent, on the roof or on the ground.
This web page is only concerned with the "live-in" type of vehicle, which I shall refer to, from here on, as an "overland campervan".
(As an aside whilst it can be advantageous to travel in groups, this works best if all the vehicles in the group are of the same type (i.e. all "live-in" or all "live-beside")).
