I've used this several times over three months on a 2013 Chevy Avalanche and it works extremely well.  It's easy to set up, easy to remove and adds a great measure of safety to moving gas cans as they can't flop around in the bed.  I used to use a bed extender on a Honda Ridgeline and it was O.K. as would any extender be on any pickup but extenders don't give the ability to draw whatever you're hauling tight to the tailgate.  This also has a secondary use--you can use it to reach to the area closest the back window to drag stuff to the tailgate area saving yourself climbing into the bed.
