We now have almost two years wear and tear on our wood floors. Since we most often boondock, we are constantly tracking in dirt, mud, sand, gravel, etc. We try to be careful and we wipe our dog's feet before she comes in if it is muddy or wet outside. Also, we love to use a couple of cheap throw rugs we bought at Target. We shake them out on trips and run them through the washing machine when we get back home. We generally take a very powerful small hand held vacuum we have at home with us and carry it in the toad.
So far, the floors show nothing of any consequence. We are perfectly happy with them and find them easy to clean and very practical.
