Unless the wood inside the RV stays wet or you are parked in an area that supports the growth of mold, mold would be one of the minor considerations. As soon as the moisture is gone and there is ventilation, mold won't be growing.
THere is probably damage to the whole floor and the bottoms of any pressboard cabinetry or built-ins. My guess is that most of that will have to be removed to replace the floor. It may be that the vinyl flooring carried away some of the water and protected parts of the floor. Someone will have to make a judgement on any of the interior being saved.
