We bought one 18 years ago and still have it. I've got very mixed feelings about it. I love camping, and at our age it's a comfy way of sleeping in a field. Most caravanners are nice people, and we've had some super holidays, mainly in France where we take the bikes in the back and use them almost exclusively to travel around. Municipale sites are usually small, clean and well-run, and a lot of French people use them, so we usually use these and get away from the Brits. I get a brilliant night's sleep in ours, comfier than our bed at home. It's a mid-range 2-berth Swift Challenger.
But ...
I hate it as an object. It's ridiculously flimsy and everything in it seems made for the convenience of cheap manufacture and not for long-term ownership (German vans are not like this, I am told). Carpet stapled down under the units. Water pipes and cables routed where you need to take half the van out to repair a small leak (that was this summer's fun and games.) Towel rail held on by two small self-tappers into 1/8" ply. Impossible to refix when it falls off, as it will. It's the exact opposite of everything I value in a vehicle, durability and good design.
I don't like the way it takes up useful space on the driveway.
I don't like towing it. It's not that I don't like towing, but it is so flimsy (again) that I am constantly in fear of things getting scraped off or falling off across 3 lanes of the M5.
Stupid, I know, but I don't like being that guy towing that caravan. As a driver, I just wish them all off the roads.
It costs more to service than my car.
We've had some good times in it, and my wife loves it, so it's not going anywhere. But if I were on my own, I would sell it tomorrow.
