im like 70% wanting to do a cap, i've got a pretty sweet leer commercial one priced out currently, that would be super awesome for day-to-day as well.
i like the racks like that too, but want dry, lockable, weather proof storage for the bed.
30% sure i might do something like this, instead of the cap, would defintiely be a cheaper option.
holds 1250 lbs, bed is still locakable, rack is adjustable to the front of the cab when not in use/tall loads... etc.

im not even sure wind resistance will matter for how stupid big this is of a truck. i think it might be like your old burban, where it just gets what it gets always no matter what
