I'm looking to buy a trailer and small car, maybe an MX-5, to tow down to France and Spain for the winter months. Never having towed behind a motorhome before, I'm looking for advice. We have a Concorde Charisma , manual gearbox, with a a GVW of 6.7 tons. On the weight plate the figure of 10,000 appears, so I'm assuming we can tow up to 3.3 tons? The MX-5 is about one ton. Can you overnight on an aire with a trailer? We tend to go non-peage and the extra fare for the trailer on the Brittany Ferries Portsmouth to Caen crossing isn't too much.
