I've been to Oradour. Here's a tip for you. You can gain free entrance to the village by avoiding the gift shop where you are led to believe the booklet they sell you is for entering the place. It's actually free to get in. It's an incredible place and so moving to see the graves and the church where the population were lined up against the wall and shot. You can actually see many of the bullet holes with bullets lodged in the wall. As you are a motorhomer there is a free Aire a few hundred yards from the town. Some of the cemetries around the northern coast are very moving. The American cemetry especially is in a beautiful location close to one of the landing beaches.
