First ever French Stopover needed about an hour or so from Roskoff (1 Viewer)

[Papa Smurf]

No idea what road number we'll be taking, just that we land in Roskoff in the evening and want to make an hours' headway into France before pulling over. Any recommendations (apart from don't go north) ? Good Aire, campsite (for 32 ft RV) or safe wild camping all considered.

Thanks,
