FWIW I had the Ford factory "ToughBed" spray liner ordered for my 2012 F250 long bed lariat I picked up in February. Have had over twenty 1300lb wood pallets pushed into the bed. Absolutely no indications of any ToughBed liner distress. Sometimes I have scraped off pallet paint left on the "liner", which disappears in time. So far happy with the product.
I work for a local municipality and all of the new trucks are coming through with this tough bed. we have not seen any failure or fatigue in any of the liners in the fleet. I will be getting this liner when its time for me to get a new truck. I was quite impressed
