I have a 2018 3500 ram cabin chassis with a flatbed. I went a flat bed to gain storage space. I drive on the beach all the time just air the front and the outside rear tires down to around 30 psi. I haul a 2011 Lance 1131. Hope this helps
Hands down go to cape lookout . Take the ferry over from Davis NC. Drive down the beach to the point . You can see the sun rise out one side and set on the other!http://cape-lookout-cabins-camps-ferry-davis-nc.com/contact
I am in NC. I have stove, fridge, tanks, sink, converter, etc. out of a 99 truck camper. Camper was damaged and I am scraping it out. You can have what ever you can use. Just have to pick it up. Let me know if I can help
