5th Wheel(2004)

On his 62nd birthday, confirmed lazybones Herbopolus grabs his nest egg and buys himself a new trailer, a fine 5th Wheel. Now all he has to do is sit back and wait for the Social Security checks to start rolling in. In the meantime, his insane brother Bananas Foster escapes from the Catalina Mental Institution and, looking for a place to hole up, gets Herbopolus to let him stay in his swanky new digs. So does their dad, a sex change octogenarian who's lesbian lover has kicked him out of the house. When the government fails to come through, they resort to collecting and recycling aluminum cans to make ends meet.
