“A trailer park with a big workshop area”
The trailer parks I’ve seen are the ones where the landlord owns not only the land underneath, but the trailers as well. That type of park is all about not spending any more than the locality requires. There’s usually a shared laundry building and maybe an old and unmaintained playground, one parking space per trailer, and that’s it.
I know there’s a more upscale type where the landlord owns the land underneath, but the tenants bring their own mobile homes. #sonTwo and his wife stayed in one for a while (but I didn’t get to see it in person). Maybe one might see extras in such a place.
