Nice! Thanks for the help there. Those numbers seem a bit high from my perspective though. But then again, the bulk of my traveling consists of driving from my home to Redstone Arsenal except for when my job sends me to places like Kauai, HI or Anchorage, AK so I don't really see that many house trailers...
I did notice too from your link that Florida leads the nation in the number of mobile homes with 841,439 trailers which is 8.9% of the total housing stock. Incidentally, Florida's numbers are over twice the number of trailers in Georgia and about 4 times as many as in Mississippi where I would expect there to be a lot more than there are.
