we stopped on 01/01/2024 camper parking area without any service, quite quiet (the municipal road passes nearby but with little traffic). (it is a shared car park)

If your vehicle is longer than 5m, leave it. Hard to rank even in the off-season, especially since it is a dead end. Better look around for a place!!

I would certainly take the advice below to heart. We thought our Camper TomTom would come out, but no. Our advice: go and enjoy one of the winegrowers in the area.
