High season now, so expect some hefty prices, avoid August if can - French Hols time.
Failing else, take a decent lightweight 2 man tent a piece and a doss bag and use the French Municipal campsites' for approx 15-20 euros a night, they are cheaper, or others camp sites on route/arrival. Plenty to choose from if you get off the Auto-routes. It
s sometimes worth stopping at a rural farm or two and asking, and bung em 10euros/night if you dont mind ruffing it. obliging sometimes. Fresh milk too , just mind the cowpats :open_mouth: :laughing: :laughing: Campsites generally don
t tend to be signposted off Auto-routes - mainly on the N routes ( Nationals) and near towns and odd villages.
Tip:-
If you do use individual campsites,or the main one/s , they will always ask you for a “carte identity” @ the reception when booking on site,
Show them your photocard licence and NOT your passport, - unless they really insist on it,
that way - they will and have to hand it back to you, otherwise if you show them your Passport - they may retain it till you leave as security for being English /British (delete as appropriate)…> don`t ask me why > but that has been my experience over many years of travelling there.
You should Never let them hold onto your passport, you may need it if stopped and it is a Valuable document .
Avoid the one at Dijon central, the owner is a miserable old cow and its a nightmare mossie ridden she-ite hole 
Depending where your aiming for and how far south/east or west your going - give yourself plenty of time - its a fair old treck - take plenty of rest breaks or site seeing. Drink plenty of bottled water (cheap at the supermarkets).
Use the Supermarkets (Supermarche) for your main shopping, and the village local for your bread sticks and croissants.
Get up early for your french stick and croissants and pain chocolats :wink: they sell out quick and are closed just before midday. Nowt worse than yesterdays crusty loaf. :unamused: If it
s market day in the town , use the stalls for good cheap fresh produce, and the fresh peaches are lovely 
Always take some mosquito repellent for the tent, the mossies love grassed areas where there is water or lakes close by.
Keep your fuel tank topped up regularly - fuel stations can sometimes be miles apart.
If you choose to use overnight/few night stop campsites, check the gate closure times , dont want to leave bike outside if can.
Good luck and happy hols , you will love it . Ride safe and ride free .
