Ground crew? You need at least two ground crew persons. We've had motorhomes and we've had hotel rooms - Personally, I prefer the hotel rooms most of the time. There was a stop or two that didn't have balconies which was a pain the butt because that meant we had to hang our stinky, moist, and salty gear inside the hotel rooms. The ground crew prefers hotel rooms because getting from point A to point B is easier in cars and parking, once you get there, is much easier to come by. Ideally, you want a passanger van (big enough to carry the whole team) and/or a small pickup truck with enclosed storage in the back. We take a lot of spare parts (rudders, boards, sails, etc.) and tools too. Once you figure in all the associated fuel costs of running an RV, the hotel rooms come out only slightly more expensive (depends on how you are stacking up sleeping arrangements).
