we recently added pop gizmos to our 23 b have only used them 2 weekends but think they will help as the bunk ends can get rather warm during hot summer days. They also help to darken the ends in the early mornings. We also purchsed have not used them yet on an outing auto sunshades and zipped them in between the screen and canvas and we think this will also help with warmth, cooling, and they will help darken as well from early morning sun. We bought the sunshades with the bubble insulation and foil on both sides.
