its surprising from what I've seen in last few days how many caravans are similar only built for 2 people, and they are 22ft long!
Very true.
We are a family of 3 (mum, dad and little miss 9yo) and we like the pop top caravans so it fits under the carport.
When looking, it amazes me the average caravan is at least 20 foot, and it only caters for two people.
I remember in the 70's and 80's when mum and dad had a 14 footer Windsor with 3 kids.
Mum and dad inside and the brats on bunk beds in the annex.
You'll be lucky to see a van under 20 foot in caravan parks these days.
