I am not sure about transportation from RV campgrounds. There is a free transportation service supplied by the city that may accommodate you. It is called Downtowner. They are a service within a 3 mile radius. Downtowner has an app to reserve your ride. One may download it and search if it covers the area where you are. The drivers were all very kind, considerate and seemed pleased to have visitors to the city. I hope this helps you.
Uber and lyft are both great resources and pretty quick and inexpensive in the area.
I really don't know either but did see some buses that was running
