I have a bedrug too, but I also have a soft tonneau on it and it gets parked in a garage while at home..
That being said, I really like the BR, as I don't plan on hauling any dirt or gravel in it either.. I have hauled firewood and to clean it out, I swept out what I could and then had to vacuum it to get the splinters out of it.
You are supposed to be able to spray it out with a hose and it's supposed to be UV resistant per the demo video on their web site..
I'd do it again if/when I get a new truck, but I'll likely be able to transfer the BR to the new truck anyway..
Good luck!
