Common Sense Note
Parents need to know that this film is premised on a tedious sitcommish conceit: A father lies to his family about the reason for their vacation. The predictable road trip hijinks include problems with the RV's septic system (sewage exploding all over Robin Williams), sulky children, RV crashes and bad roads, mud and rain, wild raccoons, hip-hop bullies, and fellow travelers ridiculed for seeming "hick." These travelers include a mother who shows lots of skin and frequent cleavage. Children behave badly toward adults, adults behave badly toward children. Language includes sexual references; violence is comprised mainly of comic antics and pratfalls.
Marie Jo wears tight outfits and shows much cleavage; frequent verbal allusions to sex (for example, "might have a shot tonight"); reference to "testicle" as a breakfast food.
Comic hijinks include the RV crashing, skidding, and banging into trees, stop signs, and mailboxes; Dad loses control of RV and lands on the windshield, whereupon he's slammed to the ground when it stops suddenly; girl throws a soda in a man's face.
Immature language and gesture: daughter gives her father the finger behind his back; repeated references to the RV as a "turd," as well as "bitch," and a reference to "Jewish people" in Hawaii.
Dad lies to his family regarding his work during the vacation; kids talk back to dad; tedious fart and poop jokes (especially concerning the RV's sewage).
