Back in 1930, Modern Mechanix reported on Charles Miller, of Portland, OR, who was rambling around the nation in a homemade mobile-home that included a plot of grass from his beloved hometown.
WHEN Charles Miller, of Portland, Oregon, found the wanderlust too much for him in spite of his love for the old home, he decided to see the world and carry his home right with him, too. So he built a complete bungalow on the chassis of his car–not even forgetting to put in a nice bit of lawn. Then he started out and since starting he has traveled over 200,000 miles and isn't through yet. Mr. Miller claims to have the only motorized house and lot in the country. The "lot" consists of a narrow strip of earth and turf.
