The product was a simple 1hr install. I first layed It in place to check its fit and while it was still in place I went under it and marked the rails placement. I drilled my holes at that time. I attached the cover, then aligned it by closing the tailgate and tightening it up while inside the bed. The bed has been water proof since its application, 4 months now. Happy with this decision and product.
Install Time: 30-60 minutes

Cover looks good but doesn't fit my 2001 Avalanche at tailgate. Needs shims that were not provided. Supplied instructions were not for Avalanche. Cover is not as sturdy as advertised (bends under 200 lbs of weight).
