The Rogue River version out of Dallas, Oregon offers more luggy tires, and you can get a lift kit installed on a new unit, or add it later. That would raise the clearance for your most vulnerable parts: the Black and Gray water ends usually on the driver's side. If you like to get your camper into less-improved dry camping spots (esp. common in the West), extra clearance could help you with tree roots or a rock, or brush tearing at your tank level sensor wires.
Also, on the highway, (like I-95!) if you are forced to straddle some tire shreds from an 18-wheeler, a bit more clearance could allow you to pass with less damage. To me, that would be more important. I would try to position the tire debris away from the driver side if possible to keep it from contacting any of the gray/black plumbing low points.
You can upgrade to tougher tires later. A higher lift is a plus, but just checking the ground and maneuvering trailer around judiciously is probably your best protection in the end. Consider that a lifted one gives you a higher center of gravity and a bit more wind resistance, which would be a factor coming across windy Wyoming. It's all give-and take, I guess. I'm always on the fence on whether I want to add a FR lift kit later or not, though I did get the big 15-235s and luggy tires with my RR edition.
PS Mom lives in Bluffton, SC in a retirement community near Hilton Head. You have great access to the Blue Ridge mountains ! We are looking forward to exploring that region in '17.
