The Boldt comes with a very nice Maxxair fan in the ceiling of the van to draw air through the cabin. Unlike the rest of the windows, the 2 front door windows don’t have screens and sometimes its nice to get air flowing up front as well. In a pinch we can lower the windows slightly, but in the evening when bugs are about it’s nice to have the front windows screened as well. The solution we found is a set of window vents from Agile Off Road. They easily store flat in the “pizza oven” and are quick and easy to install.
