I'm not sure if I'm going to make that meetup this year but you should go if you can. It's a fun group. Lots of families will be there, and lots of offroad/overlanding enthusiasts but not a lot of vans. They usually have trail options for different levels of interest.
Offroading in the Southeast: The problem with offroad in the Southeast is that there just isn't a lot of it. I would jump on as many of the get togethers like above that you can because that way you have like minded folks and help as well as learning about good places to go. I do a lot of fire roads and light offroading but in our part of the country the offroad that is available is either just a gravel road or incredibly technical, meaning serious rock crawling for Jeeps and the like. I have found overhead clearance to be the biggest obstacle for an SMB. We're a LOT taller than Jeeps, which is why I've started carrying a chainsaw when I explore new places.
You MUST plan a trip to Moab and just explore. It's well worth the drive and will open your eyes to what a Sportsmobile was made for.
Oh, and I would love to meet up and explore a little! North Georgia has some good spots. Keep in touch.
