Over the Cab Rack with Camper Shell

Does anyone know of a good over the cab rack that will fit an 05 with a camper shell? Wondering how that might mount with the plastic bed. I can't seem to dind one that will work with a taco. I have thule rack on the shell now, but it just doesn't work for long stuff i.e. trim, canoes, ladders etc. Thanks ahead of time.

 

All of the over the cab rack / cap combos I have seen are custom .

I got the Leer RCC commercial cap that comes with the DeWalt Pro Rack crossbar system , they also sell extension bars in 80" and 96" ( from memory ) .

I am going to get a set of the long extensions , bolt them under cap crossbars and add a third crossbar at the front .
