I know the members on this forum can solve any problem, from what is the best hitch, the best tow vehicle, the best tires to put on your trailer and many more real world problems associated with Airstreams. Today I'm going to present another "big problem"!! For those of us with truck caps, or "toppers", or "camper shells", I'm going to ask "how do you clean the back window of your truck, and the front window of your topper"?? Many of us don't have a sliding or opening back window in the truck, and trying to clean the windows between is a real nightmare. What do you use?? How do you clean in between?? Is there a commercially available tool or specialized piece of equipment to make this chore easier? Have you built or designed such a tool??
