CBI Offroad Bed Rack and Waterport mounting options.

Here is my plan. I am getting the CBI Offroad Tacoma Roof Rack Height Bed Rack, and at some point I plan on getting the 3.85Gal Day Tank Water Port.

I have done some research, however as a general consensus, the waterport mounts seem only applicable to Roof Racks and not Bed Racks. I am wanting to ideally mount it to the side of my bed rack when I get it, however before I buy the waterport, I would like to get a plan of what I am going to do to attach it to the bedrack. Looking to just DIY it since I haven't seen any applicable mounts.

If anyone has some ideas to toss around, I would appreciate the help.
