Query: 4 inch rip after 3 hours!

This bag ripped along a seam after only 3 hours on the road! I could see where the puncture holes made by the needle of the sewing machine had run off the material at the seam. If Lund had done some QC I think an inspector would have rejected it.Also the inside plastic lining was all shredded. No more "Lund" products for me!Amazon gave me a refund.
