Shouldn't really be a problem finding nice RV campgrounds all along the way. Pembine, great campsites in the Nicolet (Chequamegon) National Forest, Rhinelander, Prentice, Ladysmith, Rice Lake (just north of Hwy 8), Chetek (just south of Hwy 8), Prairie Lake (just south of Cameron), Barron, Turtle Lake, and St. Croix Falls. This is a corridor heavily traveled by vacationers and there a many great camping opportunities. Good Luck!
