When I was in the Army I was sent to Washington D.C. in the spring of 1970. My ex-wife and I bought a new "New Moon" mobile home. It was 12' x 52' and we lived in a park in Gaithersburg, Md. When I was discharged 15 months later the Army was kind enough to ship "tow" it back home to Los Angeles for us.
Despite it's size I don't think it weighed that much. It rode on 4 of the 14.5" mobile home tires. The walls and everything inside were pretty light weight. At the time we were told they were good for one long or two short moves.
The thing that I remember well was as the truck was parking our home in the new park, I noticed something on the hitch as he was jacking up the tongue. I reached over and grabbed the ball. It was loose and after looking closely the nut was backed off about two full turns. This was after towing my home with everything I owned in it about 3000 miles.
We sold the trailer about two years later for about the same as what we paid for it which I think was about $5000. I had no idea our trailer had a movie star in it's ancestry.
