Also a PITA to pack up everytime you wish to go out more than a few hundred yards.also on motorway services caravan has to be locked to car and a person left with the car/van, if stolen insurance void also van on site has to have approved hitch lock and wheel clamp or insurance void also some insurance state van must be alarmed also too much of a minefield.
you may find car insurance void if you don't have separate insurance on the van
you need to check
that van is max length allowed be aware of max weight of van pulling it with disco not a problem vosa do stop motorhomes and vans lots of problems for over weight as most are
motorhome much less bother but a lot more to buy
