The Munros are a typically American dysfunctional family, complete with rebellious, uncommunicative offspring and baffled parents. The movie follows their misadventures when they rent an RV for a road trip to the Colorado Rockies, where they ultimately have to contend with a bizarre community of campers.
Robin Williams tricks us into believing he can control his inner maniac beyond the film's first 15 minutes; when he fails, any hopes of RV going off-formula are dashed.

There are some sequences where you will love the characters and others where you can't stand them. Hmm, maybe RV is close to the real thing after all.
