I have the Tri Fold on my 2011 Ram. Very easy to put on and to use after it is on. There are 2 screw type clamps at the front and 2 lever clamps at the back. Makes it very easy to use the bed of your truck if you have something large to haul around. There are also 2 locking straps to secure the cover when you have it folded up. Takes no time at all to install, although it took me a bit longer because I am particular how it went on. I looked around quite a bit before deciding on the TonnoPro. I recommend it.
