Demountable camper group

Hi all. Currently a caravaner. Considering changing to a camper. I’m intrigued about the versatility of it a demountable but want the luxury of a 4 berth for space enough for friends as rather than family.
I think therefore I could be looking for something on a double cab t5/transit style van.
Do these ever come up in the UK? If so, what sort of budget will I need?
Thanks for reading
Cheers Nick

Hello,
In terms of large truck campers, you would be looking at an American Lance or similar but would need US truck for it to fit,
their campers are to big a floor area to fit a euro or Japanese pickup,
combinations come up for sale in UK, this one was last month;

Just about all demountables are same sleeping layout with fixed overcab double bed, and convertible seats/double bed immediately below.
so in terms of any separate or divided off areas for sleeping it would have to be a caravan still.

Great advice
Cheers
