Depending on the loads you're considering and the OEM wiring, you may want to upgrade some or all of the wiring involved.
I prefer leaving OEM wiring alone or abandoning it in place, and installing an independent fuse box for these uses. You gain full knowledge of the auxiliary system, and remove concern about overtaxing whatever the OEM considered good enough.
A buddy pulled the box and built a deck for his 2019 F350 CC. When he unplugged the taillights the 2 front (not the back 2) power windows stopped working
