Aint the truck for that travels with Charlie shit, but ok. I'm all for the topper logically, shit, logically I'm all for doing shit to a truck just because it looks cool and you want more utility— just confused is all about the roof rack given your justifications. If you just want to do it, fuck me, but don't tell me it's because of reason X,Y,Z because I'll pick it apart for reasons X,Y,Z ya know.
It's a performance oriented truck and then you want to put a bunch of heavy shit as high up as possible, it's confusing lol. All that bullshit said, check out LOD, they have semi modular systems for all that stuff and they are solid as fuck.
