Is your plan to make it removable? Big windows!
I plan on leaving it on . It is removable but it is bolted in quite a few places so it would take a while to get it off. It is a dedicated camper for now.
I wanted big windows for a more open feeling inside and for good cross ventilation. One of the things I don't like about most campers is that there is only one decent sized window on one side, and IMO you need more.
