Follow That Dream(1962)

GO! GO! GO! It's Free-Wheeling Fun!

When the Kwimper family car runs out of fuel on a new Florida highway and an officious state supervisor tries to run them off, Pop digs in his heels and decides to do a little homesteading. He, his son Toby and their 'adopted' children—Holly, Ariadne, and the twins—start their own little community along a strip of the roadside.
