I know of double-wide trailers but never a double-long one. For the lack of a better explanation as to what this is, that's what I am calling it. Looking closely it doesn't appear to be a make-do-slap-it-together modification. The rear half has the exact same accent trim only placed lower at the base of the unit.
Zooming in I can see that the rear end tapers back in like the front does. It is possible two units were joined together butt to butt with four identical doors cut and installed. Those standing poles indicate the additional roofing continued all the way along, but some has since been removed. It looks like a mobile home motel in a strange sort of way.
