As a family, we are pretty keen campers, and regularly, explore Cornwall and Devon in our van. Whilst the kid's are still small I am interested in taking a fly drive holiday to the States, hiring a larger camper at the other end. I was hoping someone may have some information, as costs seem to vary tremendously, with clauses about miileage etc. Has anyone tried anything similar? I would be interested in problems or triumphs along the way too.
