Caravanning is another of those activities that I assume to be a British thing. I know travelling people the world over live in caravans and the US has its trailer parks, but holidaying in a mobile caravan strikes me as being a British thing.
We had a caravan when I was growing up. Not a mobile one - a static one on a caravan site only about 30 minutes drive from our home (admittedly it was in a beautiful area of the Northumberland coast, but still it seemed a bit silly).
I've no idea what possessed my parents to buy it - we always holidayed abroad. We used to visit the caravan for the odd weekend here and there, but more often than not we'd just go there on a Sunday - it was near enough to do that easily. Ridiculously, my mum used to still cook a full Sunday dinner but just relocating it to the caravan so the car would be loaded up with a roast and ready prepared veg, for her to cook there.
Often, it being the north east of England, the weather would be bad, so after lunch we'd stay in the caravan, watching Bonanza on a portable television before returning home early evening.
