Just returned from Ohio and North Carolina. Good trip, even with a trailer flat tire in Ohio. It happened in a 'convenient' place. However, the front roof vent opened itself while underway on our way out and on our way back. We made especially sure that the vent was properly closed and assume that road jiggle made this happen. Any suggestions on how to keep it closed all of the time? Thanks. Ken and Olga, Northwoods
