Wish I could help........Just don't do much of that with my lowered 2 wheeler........

If you're going to be at the air base you won't have any trouble finding where the 4x4 guys go. I heard about a spot out Rte 61 toward Walterboro and I'm sure there are more.
There's a couple of 4 wheeling shops on Dorchester Rd....toward Charleston from the base too.

If you need help with any of your wrenching, I can point you to a couple of good honest shops. Call me at 843-906-6244......be glad to help.

Thanks for your service!!

Bob
