How do you seasoned Boat and RV managers retain your customers in the off season?

Just bought our first Boat & RV location in Florida back in May. We are doing well filling the site last 3 months - But my question is, when we closed on property in May we saw a ton of customers move out telling us they would be back, and old owners held spots for them. We told them if we have spots we would gladly rent to them again, I understand they do not want to pay while they take their RV across country for 4-5 months.
