I have it and it washes out really easy with a pressure washer. I have hauled ashes, mud, and had a backhoe dump way too gravel into it from about 4ft above the bed and no damage occured. Glad I got it.
Thanks for the info. The JD sales rep advised me against it and suggested the mat. I repeated my desire to get it and he just advised not to so in order to keep the peace I went with the mat. Kinda Strange for the sales guy to do it but well I figured I could have it done later (LineX) for less maybe. I'm glad you like yours as I thought the same. Funny salesman for sure!
Let me know how the LineX works out... I am thinking of having the under side of the entire bed coated so that the mud will rinse off easier and the rocks won't chip up the paint. Let me know what they charge you. Thanks
