Depending on vehicle, installation could be difficult.
Installation was difficult on a Tacoma with factory bed cleat system. I would recommend a pair of vice grips as helper hands. It should be a straightforward install but with my unit, 3 pre-machined mounting holes did not match up exactly with the rail mounts (to be mounted behind the rail). This led to several cross-threaded factory nuts requiring a mig weld repair. So it became an all-nighter but in the end glad it's done. Cover is a good value and quality is excellent.
