Review on Durable & Dependable: Tuff Truck Bag - Waterproof Heavy Duty Solution by Justin Frazier

Just made this on a 1000+ mile trip with a full pack. In some places along the way it was pouring with rain and not a drop got in. The included bungee straps aren't useless, but they're close. I bought a cargo net to put on top to hold it (which wasn't really necessary) and ended up just using the cargo net straps to secure the entire load. They say it doesn't need to be secured as the weight holds it down and it may. But I didn't want to rely on it. (Also, if it ends up empty, secure it with a cargo net so it doesn't fly out.)
