RogerL - There probably aren't caravans about with the specs I said - what we have is an 80's Sprite Compact Pop-Top (similar to a Musketeer in layout). With the lid down it is only a few inches higher than the RR, so makes for a very docile and economical tow. I can even see straight through it on the interior mirror.
It becomes clear, from this and other discussion here, that the towing rules are already more complicated than they should be for easy comprehension, and I am sure there are a lot of people out there who are towing illegaly but don't know it simpley because they have misinterpreted the rules.
And I suspect many will continue to get away with it because the police are not necessarily much more expert in more arcane aspects, such as the Hobby issue, and towing cars behind motorhomes, currently under discussion elsewhere here.
