Which actor plays the patriarch of the Gornicke clan in the 2006 comedy "RV"?

Jeff Daniels plays Travis Gornicke, the patriarch of the Gornicke clan, in the 2006 comedy "RV." Travis is the relentlessly upbeat father of a family the Munros meet during their chaotic recreational-vehicle vacation.

Directed by Barry Sonnenfeld, "RV" stars Robin Williams as Bob Munro, a stressed beverage-company executive who secretly changes his family's planned Hawaii holiday into an RV trip toward the Colorado Rockies. The Gornickes, who travel in their own RV, become both a source of comic irritation and an unexpected support system for the Munros.

Daniels' character is paired with Mary Jo Gornicke, played by Kristin Chenoweth, and their children Earl, Moon, and Billy. The role is easy to confuse with Bob Munro because Bob is also the patriarch of a family and the film's main character; however, Bob is played by Robin Williams. Daniels' Travis is the exuberant, unconventional father in the neighboring Gornicke family.
