Undercover Flex

So someone here must have tried one of these by now. I have one sitting in it's box in the back of the truck now, but we are expecting heavy winds and rains shortly. Is there anything I need to know before I begin this install. I watched a couple video's and looks straight forward, then I looked at the Tacoma, and it seems the less simple. Just looking a little advice before ZI do it the hard way

 

your confidence in my abilities is overwhelming. I know the install can't be to hard, just hoping for any tricks, like remove the bed tie down racks. You know moran stuff
