All of the mobile home movie mayhem demonstrated the impracticality of trying to transport the newer 40-50 foot -8' wide- rigs. By this time, the mobile home concept was changing. Units were simply becoming too large to use as travel-type trailers.
Buyers now purchased their house on wheels and made it stationary...preferably at one of the many mobile home parks around the nation. Of course, this began to incite the ire of local governments, who bemoaned the tax-free status enjoyed by the typical Trailerite family.
Moreover, the real estate industry was lobbying hard to establish local zoning restrictions that would make it illegal to set up a mobile home on a single lot. Simply stated, you would either have to park your mobile home on a postage stamp-sized park lot or else have to buy a house, preferably from a realtor.
In the mid-20th century, before "house trailer" had a negative connotation, the typical trailer park was promoted as a vacation or retirement haven. Several luxurious amenities, such as tennis courts and swimming pools, could be included...as shown by this 1961 advertisement for a St. Petersburg, Florida Tin Can Tourist community. Monthly lot rents in a high-end park ran between $50 and $125 per month.
