4 bolts through the top rails and it's all set. It does sit very snug though and the height of the system is adjustable so the weight is not just all on the rails or the bed.
Same as Zach just four bolts and it's good. i just took my rig off my truck today o clean I and do some small winter maintenance and its as easy as unscreew th. Bolts and two guys can lift it off carefully.
Holes in top rail were preferable to holes in bed which allows chems through and rots vital parts of the underside of the truck. We seal in the beds with hot spray or alike bed liners. See video.
That's exactly what I was thinking, I am totally against drilling into my new trucks bed, call me crazy but I try to keep my stuff perfect, makes a huge difference in resale values.
Hopefully we'll come up with a way to secure without drilling.
Maybe I'm weird, but I've had mine for 4 months and have yet to mount any clamps or drill holes into it at all.
Nice snug fit - it has maybe a 1/2 inch play in the bed of the truck, and with my 100 gallon tank full plus my batteries in there, it doesn't budge at all.

I took my skid off and when the guys put it back on they didn't bolt it down and when it had bleach in it we couldn't move it. They were driving too fast and went over a rise/bump it lifted a little bit from the bed. Bolt it down ASAP.
