As a new caravanner, I wonder if anyone can tell me what the term 'Design Weight' means? My van is a 1989 Cosalt Abbey Lincoln whose plate states 'Design Weight 935kgms' Is this the unladen weight or the equivelent of the mtplm? It is only a 2 berth but has all the extras of the day such as a casette toilet, shower, oven etc... It pulls superbly with my 2002 Nissan Almera Tino 1.8 SE but as I am due to change my vehicle shortly I want to ensure that I pick a car with the corrrect kerbweight. Many thanks.
