We went for a pop top because there are 3 of us but having had one, I wouldn't buy a T6 sized camper without one. Even on the few occasions when just 2 of us have been away in the van the first thing we do on site is pop the roof and the last thing we do before leaving is take the roof down - it just gives a feeling of so much more space in the van and makes it more comfortable to use. You will also find that having the roof up will give you a comparatively cool van in the summer.
