Somebody posted an ad on Craigslist and, yes, that is what the mobile home actually looks like:
Hi, I have a tiny home that I would like to either put in a vacant lot or a backyard. It is tiny. 20 feet long and 8 feet wide. I will be moving it in Fall and looking for a place to bring it to!
If JP doesn't work out (you know how pesky our zoning codes can be), there's always Boston's only mobile-home park - the Boston Trailer Park on VFW Parkway in West Roxbury.
