All the Cap Finisterre dog friendly cabins for next October (2019) are now booked we are now looking at Portsmouth to Caen and on to Bordeaux via Rennes/Nantes. We are Class 3 (over 4m high and 5.5tonnes). We can get south from Caen to Nantes on good quality dual carriageways but southwards, the A83 Autoroute to Niort (24euros) and then the A10 to Bordeaux (35euros) are expensive. Any recommendations for non-toll routes that will get us from Nantes to Bordeaux on reasonably smooth roads? My route planner recommends Nantes - Cholet - Parthenay - Poitiers, and then the usual N10 to Angouleme etc but it may be infested with roundabouts and sleeping policemen! Advice on a good route welcome.
