You are absolutely correct, it is only a guide, it is not the law, however I have been in the caravan business for the past 25 years or so and we always recommend 85% many caravanners claim to be experienced, most of them cannot even reverse with the van on their car.

Also they use their vans 2 or 3 times a year that does not make them experienced, we are fetching caravans into our premises every day of the week from all over the uk, and we would not tow 1 to 1 i.e 100% that would be shear stupidity.

The 85% margin is a recommendation of the caravan council of which our manageing director was chairman a few years ago, and also a recommendation of the caravan club.
