I can carry my house in a rucksac to the remotest parts of the world
So can I. I have a lightweight bikepacking setup, and I have a lightweight family camping setup too. My next camping trip will be with the family in the tent, cos we have to take it all on a plane.
But for a weekend away in the car, which we also do, the caravan does the same job as the tent but is much more comfortable. That’s really al there is to it.
You don’t have to be one of those insane old people who sit in their caravans watching telly and treat caravanning as an activity in itself. It’s just camping, but comfier.
