Love Nest on Wheels is a 1937 Educational Pictures short subject directed by Buster Keaton and Charles Lamont.
The film is notable because it is one of the rare times that Buster Keaton appeared onscreen with his family, with whom he had performed in vaudeville.
Elmer and his family run a small rural hotel, which is on the verge of closing unless they pay their $350 mortgage by the end of the day.
Elmer convinces them to buy a trailer belonging to him, reasoning that they can spend their honeymoon traveling the country instead of staying at the hotel.
St. John's "Uncle Jed" characterization, with scruffy beard and old clothes, became the basis of his "Fuzzy Q. Jones" character in western features of the 1940s.
