Rolling it up is a little stiff right now on a 5ft bed but it should limber up before long. Installation was easy.

Very good looking cover, easy to assemble. The side rubber gets really flat, which is great!

Great looking and sturdy. Beware if used in Northern Climates: cover can freeze to tailgate so you must make provision if traveling far in cold wet weather.

Everything went pretty smooth for two of us. I had a little difficulty getting it to latch correctly. Where the white plastic pins come out, the casing around rubbed a little. So it was hard to snap it in. I lubed it with silicone and tried to move the latch assembly in, but really couldn't gain much. Still rubs a little. Hard to snap in but I think it will wear in after awhile. Over all not that difficult to install.
