I'm not sure that is possible.. Everything I've been able to get onfo wise says roof capacity of 200 lbs.@Crschol7 basically a bed rack pioneer! You the man for the pics.
What I thought was very reassuring were the factory screenshots of the frame showing that it is definitely made so one can install the rack on it. The only thing left I'm worried about is finding the proper one so I can install a rooftop tent and take it offroading without it collapsing.
No idea if possible to incorporate a Roof/Bed rack to allow for more weight.
