Put the k-cover on today. Thanks again to friends here who posted source and tips. All very helpful-especially the preassembly of the brackets. Made it a breeze! It's just what i wanted. Good looking and easy to get into the bed. Not watertight-but doesn't claim to be. Excellent directions. Will do the modification to the back bracket as suggested here too so i can use my bed extender. You guys are the best.
