Update:
My question is - if I bolt into a pre-existing hole in the truck frame, (recent F-350) with a new, stainless steel bolt…. would the frames coating (anodized?) stop it from being a good ground?
The truck frame isn't anodized, nor is the hitch. The hitch is powder coated. The powder coat is preventing the wire from making contact with the bare metal of the hitch.
Connect all the lights to a 4 pin male connector, and plug them in to the truck's 4 pin, DONE.

and they said: I HAVE to ground the white ground wire to the truck frame.
I asked “could I just wire the white ground wire to the 4 pin flat trailer lights plug?” and they said it likely will *not* work…. and i’d need at least a 12 gauge wire … but it is better to ground to the frame.
No, you don't have to ground the lights to the truck frame, you can connect them to the 4 pin trailer pigtail. In fact, connecting all the lights there is the easiest thing to so.
For two tail lights, 12AWG is totally overkill. The people at Blazer aren't very well versed in trailer/truck light wiring if they are claiming you have to use 12awg for a simple pair of tail light, and then also claiming lights won't work when grounded through the 4 pin plug.
