All the 60s classic British vans rusted like billy-O!

The split-screen VWs are death traps in shunts (look where your legs are), and forget about doing more than 40 if there are cross-winds.

If you want enough space for a loo and a shower, (as well as cooker, fridge, wardrobes and beds - oh, and space for the guitars and mandolins and squeeezeboxes - if you go for a campervan you will be driving round the rest of the year with something unpleasant and thirsty.

As said above, you have to unpitch to go to the shops.

Levelling a van-based home is much more difficult than a caravan, and old fridges have to be within 3 degrees to work and stay working - modern ones will tolerate 6 degrees. Or you can go for a HGV-sized US based monster at 5 mpg with hydraulic jacks at each corner.

I think tent or caravan is much more sensible. If you want your own loo and shower that leaves caravan.

Small caravan and Volvo turbo. Drive an appreciating, fun, classic the rest of the year while the caravan is in the drive. The Volvo has plenty of grunt. I have succeeded in turning a generator over in the back of the Volvo (with the van on the back) while being rather annoyed with a Ford Focus.

Or get really radical and go for a conversion on a LandRover 101V8 or a WW2 109 Officer's sleeping quarters. Slow, thirsty, noisy - but GRAND.
