Greetings and welcome to the forum, I'm new too.
My family and I will be heading to SC for our first trip in our new for us "vintage" motorhome.
My wife is from the midlands (originally from the upstate) and we'll be visiting her family there, then hopefully getting to one of the many fine beaches there.
We tent camped in Edisto a few years back and even got a picture of our campsite on the Edisto Beach Scenic Byways website.
If you click the link, we're the ones on the left side.

My wife found it when she was searching google images "Edisto Beach", she said "there's us with the Avalon", I said "Wow, we're famous"
Anyhow, good luck with you new setup and safe travels!
