I have never lived in a trailer or a trailer park, but I have camped and motor-homed:
1. Community is important and we need to work on making our neighbourhoods more "community-minded", but that takes time, effort, and ingenuity.
2. My biggest complaint about most of the trailer parks I've visited is that there isn't any land to garden. It would help with so many things if we had more of a model like the Brit's do of "allotment gardens".
3. Nostalgia is a real thing. It usually pulls out the best parts. Our motor home had no spot by the door to put wet
boots. Or a decent bar over the small "bath" to hang drippy things after carrying them that far.
4. Regardless of item 3, living smaller has great appeal. Most of us don't need half of what we own most of the time. I wish tool-lending libraries were a thing. I wish community centers offered use of a canning kitchen for those few times I *really* need a bigger space to work, without charging more than the canned goods are worth.
I hope you keep finding ways to take the best bits of trailer living and trying to reinvent them in the situation you're now in. Be creative! Think outside the
box trailer.
