There are several National companies that deal with flood damage. They will probably load the coach with dehumidifiers to dry out things as quickly as possible and then take care of any mold that may creep in.
Your biggest problem may be the floor underlayment delaminating if plywood, or just coming apart if particle board.
AFTER everything has been dried out, check all of your electrical.
Shut off water OUTSIDE whenever leaving the coach, even if just for a meal at a restaurant. Leaks will always happen when you are gone.
