I've stayed a couple of times for a week at the Mt. Pleasant KOA. A beautiful setting, and nice folks running it. There were several full timers staying there. If you're heading south on US17, its on the left. And before you get into Charleston. Downtown Charleston's a very busy place at rush hour if you're pulling a toad and trying to turn around. Don't ask how I know that.
Retired and visiting as much of this beautiful country as I can.
