to add to all of this here: ātrailersā are often thought of as the mobile homes that you can pick up and tow, but they can also refer to mobile homes, what is literally a chunk of āhouseā that can be loaded onto a flatbed and transferred over large distances⦠i used to live in a double-wide one, (literally two slapped together) theyāre MUCH MUCH cheaper than standard housing, easier to put together, but generally dont last as long as a normal house does.
and yes, a gathering of such mobile homes is often still called a ātrailer parkā, as the homes are arranged in such a way that any one could be removed and replaced with another similar home.
you could always build a new map tile for trailer park generation that includes multiple parked RVās and such.
