Campsites in France - are they really that good?

Hi, Has anyone rented a mobile on a campsite that would accommodate a travel cot?? We don't really want a long drive when we get to Roscoff, so that's why we were going to Brittany. We would probably travel as far as the Vendee, but I wonder are we going to come up against this problem wherever we go?? Please help. I didn't find the right solution from the Internet.
