Hello to all! I am new to the forum and this is my first post. We just purchased a 1992 26 Voyager. Working on a couple upper wall leaks but everything seems to work well. As we were towing it home 125 miles I kept waiting for a rock to take out the front window. Is there supposed to be a cover over it for towing and are the expensive? Are there used ones around? Silicone vs caulk for the leaks?? Thanks
