Strapping a load atop tonneau cover

[Ms5606]

2022 Limited Longhorn HD WITH Rambox AND a BAKflip hard folding tonneau cover. Have not done so yet, but considering how I might place a large/light load on top of the closed tonneau cover AND STRAP IT DOWN. I note a couple of slots on the frame rails in the rear wheel wells ( but this would put a lot of pressure on the plastic wheel surrounds) I can’t really see a “good” way to find two fore and two aft anchor points… ideas?
(I’ve also considered that I would have to “sleeve” the tie down straps with some soft material so as to not scuff the paint)

Never strap across the body anywhere, does the truck not have stake pockets or do the ramboxes not have them?

Rambox has no stake pocket. Have looked for some decent looking system I might modify somehow fore and aft of the rambox, but not found anything remotely suitable
