We travel to and stay around Mooresville/Lake Norman so I am familiar with these:
Lake Norman Motor Coach Resort. A little off 77 but is a very nice park with a great view.
Relatives stayed at the KOA I77 = not that great... convenient but I wouldn't stay there
Lake Norman State Park - super quiet, wooded and inexpensive.
