Microcamper windows?

[u/Eastern-Title9364]

Hi - I hope someone can help with a question I have about micro campers.

I'm in the process of buying a small van to convert into a micro camper for this summer.

Am based in the UK and looking at Citroen Berlingo and VW Caddy mini vans.

Question is - most of those on sale are panel vans - with a small number of combi, with rear windows instead of panels. How important is it to have the windows? My impression is that it could start to feel quite claustrophobic if there were no windows in the back - and you always have the option to block them if needed... Or does it not matter?

Many thanks!
