Well, for starters, I tested the bag 1,300 miles in dry, hot, and humid weather and it held up. There were a few stains from the long ride, but nothing was torn and it held up well to the elements. The two things I hated about the cargo bag were that the protective mat never stayed in place and flew off somewhere after our third fill-up. Twice I moved the mat at the bus stop because of the annoying clapping on the roof, it turns out to be a sack. No matter how I adjusted the luggage from above, there were excessive hits against the roof. Sometimes more than others, but maybe that's because I've been driving at 75-85 mph at times. Assembling was pretty quick. I have a solution that worked in wet weather. As the seat belts are tightened to weatherproof the vehicle, there will be wind noise and water will seep through the seat belts when it rains. What I did against the rain was spray waterproof spray on the hellish straps and the part of the headliner that the straps rested on. I didn't feel like water got in.
