Welcome to the forum. Hope to have you share information with all of us on travels and RVing experiences.
We live within about an hour of there and have visited Amicoloa several times, but found the CG too steep to try with the MH. You must think about stopping the rig as you come 'down' the grade as well as just being able to go up.
We would not camp there. It is as steep if not steeper than Blackrock Mountain SP near Clayton, Ga on US441. *shudder*
OK for small rigs, but anything of size will have a difficult time.
