This does not exist at all, I have already suggested the change to Camper Contact.

do not understand that this is seen as a motorhome. even the basic camper will not stand here

I would skip this place. The positive reviews for this place probably belong to the other place in Honfleur, which does have amenities. This is a parking lot for cars where campers are also allowed. Passing is another story. Due to the narrow streets also very difficult to get there.
