An ancestor of the modern RV
To provide temporary housing for defense workers while more permanent quarters are being built for them, this caravan of trailers crosses Memorial Bridge, Washington, D.C., on its way to Wilmington North Carolina.
In the months before World War II, trailers are being used all over the United States to provide this type of emergency defense housing. This caravan of 50 was the first shipment of more than 2000 currently being constructed.
