Our MH is 3.05 metres high. We were charged €14.40 at two peages on the A63 south of Bordeaux, classe 3. The classe 2 rate was only €5.20. We didn't know at the time you could query the amount. What made it worse was that according to my atlas ( admittedly 2013) most of this road was toll free. We don't normally use toll roads but there does not seem to be a N or D route running from Bordeaux to Bayonne.and mostly it will virtually double the toll, stick to non tolls, no difference then
