I've been going to folk festivals for years with frame tents and then trailer tents - they all took ages to put up and got hot and tired before the festival had even started.
On getting a campervan, I turn up at the site, put on the handbreak,then put on the kettle (sorry, that's a metaphor for opening a bottle)!
I wouldn't be without now. The noise of the camp site doesn't penetrate like it does through canvas. The downside is that I have tended to sleep in as the sunlight doesn't get in either!
The van I've got is on a short wheelbase FIAT Ducato,with two single two metre beds, loo, shower, cooker, fridge, loads of storage and four proper, belted, forward facing seats. It's a real TARDIS, huge on the inside but fits into an ordinary car parking space (apart from the extra height). It drives like a car but with the added advantage of the extra height which is good in traffic and also for seeing over fences and hedges...
However, I have recently moved to live in Brittany and though I would love to keep my lovely RHD campervan, it is going to be more practical to sell this one and buy a LHD one. So get in touch and we can discuss further.
Talking of France, we used the van whilst house hunting and travelling around from the base of a rented cottage, we covered 12000 miles in 9 months and only paid once to stay on a "proper" campsite. All the other nights were at "Aire de Service" or "Aire de Repos", places actually set aside for campervans to stay overnight and to empty and refill water, loo, etc.
