We have lots of windows of good size in our Escape
19. We do like that for when inside, either laying on the bed, or sitting at the dinette.
But, like others have eluded to, their need is hopefully minimal. We prefer to be outside as much as possible too. Most of our time spent indoors is task oriented, or at night time, so the windows are not that important then.
All this said, I still like to have plenty of window area for those times it can be taken advantage of. They do stop you from feeling as closed in as you would without them.
