Review on ROLA 59102 Wallaroo Cargo Bag: Ultimate Rainproof Expandable Hitch Tray Carrier in Black by Gabriel Salleh

I bought this bag new to fit in the trunk of my VW Westfalia Camper Van. Many owners of these vans report that they are perfect for a standard fiberglass trunk design cargo bag. I love the bag's design, the thick, durable material that feels premium and weather-resistant, and the strong zippers. a new tarp in the bag to wrap my "just in case" load, as well as a much larger tarp fully double-bagged on the outside for PNW rain as I drove the freeway south into the desert. My ROLA bag stayed closed and tied to these two tarps and in only 2 rains the cargo was wet unless it was in a pond with about 3 cups of rain water. it goes on The problem. As a full-time van job, I don't feel ready to publicly empty my entire cargo bag every time I dare to land somewhere where I can unpack and stand still for days. it's unpredictable and quite annoying. I don't know what to do next, this seemed like the best thing, but I had to wash and dry my load twice in 4 weeks. it's tiring.
