Throwing my 2c in. I had a rollx tonneau cover on my tacoma and build a rack to go over/through it. Yes, it "destroys" the tonneau for resale as there are 2 holes towards the front of the cab, but I would build the same thing again...I might do it for this truck.
The tonneau rolls up (on top, no canister so you have access to the entire bed) and under everything on the rack. The rack was mounted to the rear bumper and the bed in the front through the tonneau. I can dig up some more pictures if necessary, but it ended up working out quite well.
