Your gonna be very happy you went with the Line-X Dutch, it's an excellent product.
When I was negotiating for my F-150 last year I had them throw it in as a freebie and am really impressed with it. I'm constantly hauling lumber, dirt, sod, patio stones, gravel, bricks and whatever else and there's not a mark on it. I just sweep it out, rinse it with the hose and it's like new again.
Like you say, it's a cheap investment to protect the truck.
