I just took the morning to install my Access TonnoSport Bed cover. There are instructions specific to the Santa Cruz and once those instructions are followed you switch over to the general instructions for the last step which is installing and putting the finishing touches on the fitment of the bed cover once it is rolled into place and ready for snapping shut and velcroing down the line along the side rails. Once I finished up the bed cover there is an included bed mat which is like a lightweight interior carpet with a foam backing. There are several places where you would drill into the bed to install the snaps permanently. For those who do not like the idea of drilling 1/8 of an inch holes into a brand new bed there are self adhesive snaps included. All together the installs were fairly simple to follow instructions and where the instructions leave off you can pretty much see how the install is going and what the next step is. Good Luck!
