Interesting article about how a car with a large number of seats ( 7 say - like some cars have ) could be overloaded just with number of people - like 7 adults. The overloading could void your insurance.
Does not mention caravans at all - but I just found the article surprising... and something I had not realized or considered....
Filling your cars seats could void your insurance
Just because your car has five or seven seats doesn't mean you can carry that many people. Read on to find out why......
My memory is hazy, but I seem to recall a conversation with a salesman at a van and motorhome show. I asked him why some seats in a motorhome were not equipped with seat belts. He said that adding seat belts would mean that the vehicle would have to be reclassified for registration purposes, and I would then no longer be able to drive it with a C class licence.
