Idiot
I just used some 1/4" u-boots I got at a local hardware store and drilled some holes right through the topper. I used some stall mat pieces to help level up the front since the topper has a taper to it. Then I applied silicone around the u-bolts to keep water out. It sits right on the topper. I've mounted it like that on other toppers with no trouble...other than a bunch of little holes when I take it off. Nothing silicone or a glue gun won't fill up though!
