An overworked executive, Bob Munro (Robin Williams), persuades his wife and children to give up their Hawaiian vacation for some "family bonding" on a cross-country RV trip. But it's all a ruse. Bob has other, more career-oriented reasons on his mind than spending quality time with his family in the Rocky Mountains. Through a series of misadventures, including constant run-ins with an overly friendly troupe of full-time RV'ers, Bob inadvertently learns the true meaning of family.
