I have a caravan although I don't live their permanently. I would love to though! It's easy to keep clean ( even your grass is cut for you), there's lots of friendly people to see if you're feeling fed up, mine is just a 10 min stroll to the beach and it has a shop, restaurant, swimming pool on site. Mine has full has gas central heating and double glazing and stays warmer than my house. It has two toilets and an electric shower. 3 beds so grandchildren and family can stay. It also has security that your can phone any time ( who would also direct an ambulance to your van). Dr's surgery at the end of the road and bus stop outside. I even get my food home delivery to the caravan. If I were more frail as I aged I'd go to a care home or retirement home just as I would if I were living in a house. In fact their is a couple on my site who's husband is very frail and they have carers come 3 times a day ( as they would in a house) Site fees are high though so you'd need to factor that in every year. A lot of things you'd be paying for in a house though anyway. rates, fuel, insurance etc (all in all ours cost £7000 per year to run but that is everything such as fuel, insurance, site fees, rates etc). The gas bottles work out dearer than the gas at home but you use less. Mine has double doors that open up with a veranda as well as the main door, that I would recommend as it stops it getting to hot in the dinner. If you buy the van second hand and not a new one you save thousands! My van was £85,000 new and we bought it at 5 years old for £29,000. It's so modern, better than my house ha, ha.
