Stone protection for tow vehicle

We have been using the Protect-a-Tow and love it. The protection it provides along with ease of use and compact storage is better than anything we have ever used. Our coach came with a heavy duty mudflap on the back but that seemed to cause more damage to the toad but after adding the Protect-a-Tow no more dings on the paint or windshield. Keeps my camera way cleaner too. Best of all it won't break the bank as it is very reasonably priced. We ordered direct from their website at the time but I've noticed that it is now also available on Amazon.
