Route to West Chester KOA

I would call the campground and ask them. There may be an old bridge to cross that has a low weight rating.

Yes, definitely call. I've been to several campgrounds this winter where the GPS would have screwed me good and one (Buccaneer in Miss) where the web site directions were downright dangerous if towing anything. They sent you over a railroad crossing where a trailer got stuck and demolished by a train.
