My sister lives in a senior park and her trailer house..sorry, MOBILE HOME is much nicer than my own older house. She has two bedrooms two baths, built in dishwasher and all the other day to day things that nice homes have. She has her own car and drives all over, but the park has meeting hall and probably swimming pool, don't know about that. I visited her during cold weather so we stayed in a lot.
I know lots of older folks who are darn tired of keeping up their houses and yards, so moved to these places. Also know a lady who was tired of her kids dumping spoiled brat grandkids on her to baby sit for days at a time, so she moved to a Senior only park and loves it.
