I've historically purchased extang covers and am now wishing I had again. This Lund was all that was available at the time for the new truck I purchased. The cover is loose in 30 degree F temperatures, I'm scared to see how much more loose it will be when the sun and temps get higher this spring and summer. The corners don't touch down, I'll be buying additional foam to make up that gap. Install is a bit cumbersome and I had to shave the pins to make them fit into the side rails.
