We normally stay at the
Oaks N' Pines RV Park at the same exit off I-10 when staying in Lake City - not great but much better than Lake City Campground. A quick look at RV Park reviews would have revealed this recent review which is much like yours:
Told them we had a 37 ft with a dolly and car in tow. About 60 ft. Got there and the only pull thrus that would work were marked for 70 ft plus! Took one anyway. All the other pull thrus were too short, not level asphalt in rough shape. Didn't much matter since it had been raining and many of the sites were under water! I don't do 50 amp hookup in the middle of a lake! Roads are way too small and poorly laid out. More rules than Alcatraz ! Small dog section, big dog section! They have to be kidding. Restrooms and showers are clean. Wi-Fi is a joke! Too weak to sign on. Cable is very basic, water pressure is a joke too! Won't stay here again. We camped here in a Motorhome.
