You should check out the
Stage Stop Campground in Winter Park just North of Orlando. Nice clean park with some room between the sites and decent rates.
Camping World and other RV dealers not far away if you need any RV supplies.
Also, it looks like you are retired U.S.Navy. You can use the campground at the Jacksonville Naval Air Station.
Here. That would be a very enjoyable stay if there are any spaces left.
Another excellent stop is
Osprey Cove RV Park located on Mayport Naval base.
If you have never done it, check out the
U.S.Military Campground website. It is very useful and contains a lot of information not normally found in campground directories.
