I would definitely recommend the VICARIOUS BOOKS all the Aires France, it is written in English and a great guide for first time in France with a Motorhome and has pictures of the Aires and a write up from the person who stayed on the Aire and sent details to Vicarious for inclusion in the book.Lots of other Publications too but you won't find an easier one for first time than the one mentioned. DO NOT SLEEP ON MOTORWAY SERVICE AIRES, as it is there that you will have trouble IE lots of people sleeping in Vans on these have been robbed whilst sleeping,especially if they have had a wine or three and sleep the sleep of the dead due to being overtired etc.France is very free and easy as regards to Wild Camping, you can sleep almost anywhere within reason and water and toilet emptying is readily available.Take reasonable precautions, keep your van locked and valuables out of site and you will have a great time.
