Look at Canvasback liners for the 2nd and 3rd row seat backs and trunk cover. They make a skirt that can be velcroed on to protect the back bumper from scrapes and sharp paws. I just posted pictures of mine today on a different thread.I don't have mine yet, but I'm getting the factory rear bumper protector and considering getting xpel protective film on the bumper - both to try and prevent the scratches from my dogs jumping up and down from the back.
Soon to be telluride owner in nyc, any recommendations on bumper protection?
