Not really connected to the fact we wander alll over the country in a trailer but CIndy’s Aunt Timmie and her husband, Doc owned travel trailers by the 1930’s and lived in them for a long period of time in Florida. They eventually moved into a fixed location mobile home with a screened room attached. I cannot imagine pulling these heavy units with cars of the era or living in Florida with no AC in these. Must be why most of the old photos, like the afternoon checker games were of people living outside.
