Joe, the mail trailer was just sold by the WB last year. As I recall, it had one door and no windows. I could be wrong, but that is my recollection.
You can see through front to back, so I doubt this is a shower unit or a pre divorce unit as someone thought(unless the dividing wall was removed by a previous owner).
I also strongly suspect that the wide blue strip is hiding a major surprise on the street side.
