Less windows the better for us.
Were old time campers and have found more windows = more heat gain and heat loss when camping in hot weather and cold weather.
When we started camping in the '60/'70s we also wanted lots of windows till we decided why bother as the curtains were closed most of the time anyway.
During the day were out doing something or looking at local attractions and only sleep in the trailer at nite....with the curtains closed.
Lots of windows don't do any good for those that like to rv in a crowded parking lot (rv park) where all you see is the side of someones rv on either side/front and rear.
