Oh I remember your post thank you for the update. You live in Manchester right? I had the same issue when I lived in Portsmouth, not with a trailer, but with a guy who owned an Airbnb telling his Airbnb tenants they could park in a parking lot with spaces that were clearly labeled for the apartment building that was right there.

It was crazy because it was a car with Massachusetts plates in my Portsmouth New Hampshire parking space with the sign directly in front of the car that says resident parking only with the address that I lived at listed. The police wouldn’t help they said the landlord would have to have the car towed, it was on a weekend so the rental office was closed and the answering service was not helpful. I ended up sitting in my car and honking the horn until they came out to move their car. The second time that happened I looked up the tax bill and I tracked down the jerk who owned the place and I let him know that his tenants were parking in my parking space and also I believe at that time Airbnb was not even legal in Portsmouth so if it happened again I would be complaining to everyone in the city. It did not happen again.
