Been reading alot of good reviews for this product.
www.lizardskin.com I agree that the peel and stick stuff can cause problems; plus it is heavy. And the factory mats and pads seem to cause problems over the longer periods. My most recent truck a 1992 model has floor rot from dirt and moisture under the mat; and the same for all the older ones i have also.
Maybe a bed liner product on the floor then the factory mat.
I still have not worked out if i could lizard skin then bed liner. Looks like one or the other to me so far.
