Ron, a caravan cost about 50% more than a car on the autoroutes, but those sections where there is a fixed charge, its the same as a car. Car is class 1, outfit is class 2!Ron,
Clive's point about the Michelin site not including the additional charges for the caravan is worth stressing - I'm not sure how much you need to add for the caravan but it does add up... the web site address should be: www.autoroute.fr/index
Cheers,
