Took over a month to receive the cover. Probably due to Covid 19 but you should know. Easy install and fit perfectly. Very happy so far with this cover. I needed a cover that would allow me to use my gooseneck trailer without getting damaged and this is the perfect solution for me.

The cables to open the top are too loose making it hard to open both latches at once. My old BAKFlip opened easier.

Very happy with the product and how easy it was to assemble. Really appreciate the video installation info on Tonneau as well. That is a great supplement to the enclosed instructions.
