Southern Crossing schedule and ratesI've taken this ferry hundreds of times during my lifetime. It's never been busy or crowded, it is a quick 30 min trip. The ferry does have an enclosed viewing cabin above the deck, very Spartan, but it is a warm place to get a good view.
Are you taking your camper with you or just a vehicle? Length wise, most rigs will fit. Boarding on the Essex side is trickier/tighter than the Charlotte side, which is quite open with easily navigated turns.
Views are pretty spectacular. I'll see if I can find some pictures to post...
