Le Mans in a Motor Home

[phardy]

Apologies, another Le Mans topic. Me and a couple of mates are on about going this year for the first time in a 7.2m motor home. What would be the best campsite to stay at or allowed on? Ideally we want to be close as possible to things, not bothered about the toilets/showers so much as we'll have our own. Anyone done it this way before? Good or bad idea?
