In reply to everyone:
Thanks a lot for all the advice so far. Lots of great information on what I am looking for.
I'm doing some general research now, with a view to buying in a few months so not looking to buy right now (for those who suggested specific vehicles selling at the moment. But thank you).
In terms of comfort/facilities, I am really going for something fairly basic. I realise it's nice to have more space and cooler kit but just having a camper at all will be a big step up for me (from a tent) and I can think about upgrading with more facilities later on. I've stayed in a tent for as long as 2 months at a time so not too worried about spending months with minimal facilities. So... Specifics:
- I'd ideally like to seat 4 people but I realise that most vans have 3 front seats, maybe I could slap another seat with a seatbelt in the back somewhere.
- I don't think I will start out with a pop-top but such a thing can easily be added later on if I feel the need.
- I'd like a gas hob with 2 burners but a farely simple one designed for say car camping attached to a cylinder of gas will suffice.
- I'll put in a basic water container but no pump/plumbing/taps.
- I need a fridge, food going off in 2 days hacks me off bigtime so I guess for this I would need a leisure battery and a system to charge it.
- I'll probably not bother with a shower initially (could well buy one of those black bag/solar heated jobs you just hang on a tree), don't have a problem with swimming in lakes or using rivers to wash (or stinking when it's too cold!)
- No lavatory. I'm not getting involved with sewage, end of
- Will use this in spring/autumn/summer/migrate with the seasons so no very-cold-weather features needed for me (if I do take it out in the cold, a good quality sleeping bag will be enough, it always has in the tent and a van offers much more protection).
- A sink would be needed.
- finally, I'd quite like to string some fairy lights around the inside for illumination!
So the overall slant is definitely towards the simple/economical/feature poor end of the spectrum. Obviously if the ideal vehicle with bells and whistles shows up at the right time I wouldn't say "no".
