Where in SE US in summer?

Blue Ridge Parkway and Skyline Drive.

Yep- Western North Carolina, Northern Georgia, Eastern Tennessee.

Before the days of air conditions, rich southern families went to the mountains (TN or NC) for the summer. Now us poor RV's can do the same.

You'll want to go as far north as you can. We full time and spend summers in the northern half of the US, but we spent a couple of weeks in June in Central PA near a lake and it was doable. Most other SE locations are too hot for us - but we don't like anything above 90. YMMV

X2 ^^ Florida panhandle in the summer? You're kidding - right?

How about the UP of Michigan or Wisconsin's Door County which has water on two sides.

If you consider W. PA, there a several options. In the Highlands just southeast of Pittsburgh, you can visit Fort Necessity (built by G. Washington after his English forces and Indians murdered a French Envoy) to attempt to repel retaliation by the French, Fallingwater built by Frank Lloyd Wright, white water rafting at Ohioplye State Park, or bike the rail to trails to Washington DC. A short distance away is the Flight 93 Memorial, and the Johnstown Flood National Memorial. A couple of hours east is Gettysburg, and then on to Philadelphia area for Independence Hall and Valley Forge. If you have kids with you, consider a stop in Hershey that has an amusement park, Zoo, botanical gardens, and Chocolate World. Not far away from Hershey is the Lancaster area, home to a large sect of Pennsylvania Dutch (Amish & Mennonite), quaint villages like Bird-In-Hand, special dining options, and other things.

Good Luck with your trip planning.

Boone, NC is nice.

Balsam Mountain campground, Great Smoky Mountains Natl. Park

Mile High Campground, Cherokee, NC

If you want to stay in the SE but remain cool you must go up in elevation. If you don't care how hot or humid it is then anywhere will work.
