We have stayed at the Rodanthe KOA numerous times with our SOB trailer (haven't been with our new BH yet). It is always enjoyable. Since I am in VA just north of King's Dominion, we always take 95 south to 295 to 460 east. I have found the ride much more enjoyable with a lot less traffic and stress, plus I don't have to turn off the gas in the trailer to go through any tunnels. I see you are in MD, so you might want to consider coming down 301 to 95.
