Hey guys. I just bought my 2004 Ram 1500 SLT and it came with one of those duraliner drop in plastic liners. I plan on eventually getting a spray in liner Rhino/Line X or similar. But we had some high winds here in eastern WA state the other day and My wife noticed that when we were on the freeway at about 70 MPH that where the bed liner meets the tailgate was lifting up badly. I am wondering if I should just sink a few self tapping screws in to hold it down or what. I think that maybe this liner is not a perfect fit for my particular bed. Any thoughts?
