All weather mats or floor liner for Itasca Navion 24J

We use a set of bathroom throw rugs. About 6 of them are good in our J. They are about 42" by 30" I think. They make things very easy to clean. Take them out every few days and shake them. This gives automatic rotation. Wash them as needed. They last about 2 to 3 years before looking bad, so we toss them and get new ones.
