We stayed in 49. Plenty of room for our 45 Blue Bird. Easiest site to access too. 57,58, 63-65, 70-72 as I recall we all long and fairly level. Trust but verify.

We have a small 26 foot tow behind so I really have paid little attention to lot sizes. The staff is very friendly, I would recommend call the park at 706-657-4050 and see if they can help you.

I'll preface this by saying I've never driven or parked a 5th wheel, so my answer is more observational. Sites 49 and up are in the east campground and appear to be more amenable to a 43' trailer based on driveway length and ability to maneuver. Sites 66 and 67 would likely fit that bill. The west rim seems to have some sites with a 50' driveway but the west rim has a lot of curves throughout that may make it more challenging getting in, but if you can do it, I think the west rim is more private and has a lot more trees. We were in site 21 in a class b and loved it! I think there are around 5 or so pull thru sites which I imagine are pretty hard to get. I found this park fills up pretty quickly so make reservations early. Unfortunately the reservation website won't let you filter by vehicle length, so may be best off calling the park staff and getting their input. Sorry this isn't more specific so I hope someone else with your vehicle size can also respond. Hope you're able to find a spot since it's really a nice place to visit.

Your 5th wheel will definitely not fit into some sites there. Best, you phone to ask where it will fit
