I always liked the looks and feel of them. But wonder about them holding moisture if/when they do get wet. I'd be throwing gear and things in there after a day on the water. And let's face it, it's a truck and something is going to get spilled back there sooner or later at least in my world? Or Oso all wet and muddy jumping in the back?
How's it for that over time?

Agree that the ONLY way to use one would be with a topper regardless.
