You would have a chicken and the egg dilemma. Artists would want some kind of assurances that buyers will be there. Buyers generally don't flock from long distances to art fairs and festivals that are not well known. Musicians that have followings and are well known want to be paid. Can't very well afford to pay for very many well known acts unless you are reasonably sure there will be a payback. Most people who do art shows and music festivals don't travel in RVs. The RV parks benefit from those events, but the event is the draw and the RV park just gets a little extra wind in it's sails. For the venue to be a success, probably 90% of your business will have to come from non RVers. Music festivals and art shows also require the co-operation and assistance from the local government and police force. Finally, do RV parks and art fairs really have a lot in common? How are kids riding bikes and throwing Frisbees going to go over with the sculptors and painters? I am with another poster, going to be hard to make a good business case unless you have some very unusual contacts ( say Paul McCartney as a backer).
