Mickey's Trailer is a 1938 American animated short film produced by Walt Disney Productions and released by RKO Radio Pictures.

Animators include Ed Love, Louie Schmitt, Johnny Cannon, Don Patterson, Clyde Geronimi, Tom Palmer, Frenchy de Trémaudan and Cy Young.

The house is converted into a trailer (with the natural setting, in the shape of a giant hand fan, revealed to be a city dump) and Goofy's car is released from the side.

When Mickey rings the dinner bell, Goofy foolishly leaves the driver's seat – while the car and trailer are still in motion – for breakfast, in which it drives through a closed road.

After several mishaps during the meal (getting hit by nearby drawers and sticking a fork into a power socket), eventually having popcorn for breakfast, Goofy notices that no one is in the driver's seat and accidentally and unknowingly unhitches the trailer in his panic to resume driving and goes on his way.

Donald grabs the phone (connected to an extendable metal arm) and desperately tries to call for help, but finds himself hanging outside the trailer's open door.

This cartoon was later adapted into a Mickey Mouse comic strip story titled The Unhappy Campers in which they replaced Donald with Morty and Ferdie Fieldmouse and Pluto.
