Ford E350/E450 Door Window Privacy Pop-Open Thingies

We just use a curtain between the living space and the cab. Not only is it easier but even with window covers, the cab is mostly glass, poorly insulated and significantly colder or hotter than the coach. Plus, if you are using the furnace or air conditioner a curtain will save you a lot of energy. If you don't have a curtain provided with the camper it is easy to cut one out of what ever material you wish then attach it to the edge of the cab overhang with velcro.
