Procedure with a caravan when arriving on site in the pouring rain.

7. Relax with a nice cup of tea and watch the campers get soaked.

Er..... I know which I prefer.
Having been a camper for years before we bought a caravan, we used to wonder what the benefits were as we had every conceivable item to make life comfortable. We had heaters, TV and all on full electrics. We only gave up camping after a severe battering of gale force wind, which did its best to uproot things. When we bought our first caravan twenty odd years ago it became clear what the benefits are, so we have subsequently replaced them with new ones over the years. They are warm and comfy, off the ground and you don't hear creaking poles when it's blowing a gale. You don't have to leave the van to use shower blocks and toilet blocks, it's all there in the van. You are never cold as you have multiple heaters and instant hot water and heated towel rails to dry stuff. They also serve as an extra bedroom for guests at home if it sits on the drive like ours does.

The downside of caravans:
You have to store them.
They are expensive if you don't make full use of them, a decent one weighing in at around £20K now, and my awning and annexe was an additional £2K, plus all the extra bits.
You have to tow them, which in itself can put some off.
Pitch fees on commercialised sites are not cheap.
I have now weighed up the cost of the van, the pitch fees, the additional fuel costs towing and we have decided to retire from caravanning. We rent a cottage at a destination of our choice now and the cost is not much different.
If anyone thinks people caravan as a cheap holiday you are mistaken. It is not a cheap holiday, as the price of a caravan and required ancillaries will get you several foreign holidays on Costa-del-bargain.
