Nigel,
Before you follow the kindly Mr Zarse's advice, and go down the road of camper vanning, you should know that these vehicles are usually herded towards the back of the campsites. This in itself, is not a bad thing, but at least at maison Blanche I think you'd need to be careful. Towards the back, near the trees there's usually a camp of Missisippi woodsman, and though personally I think it adds a bit of cosmopolitan colour, with the evening air full of the sound of wailing and the strains of fiddles, some might find all the squealing a little offputting. They're a pretty intimidating crew alright. Early in the the morning the air is full of a different kind of straining, but I think that's from a little further upfield. Whether or not these guys paddle their way to LM through the mist in beaver skin covered canoes or not, I can't say, I've never dared asked them, but they sure can put away sourmash whiskey and strike a mean deal trading furs and other small critters. Good lads though they might be, I couldn't recommend them for any orthodontic problems you may have.
Other than that, you should be ok.
