I think they don't want you drilling into anything that's under the roof sheet metal. There will be electric harness wiring, roof supports and the headliner to poke holes in. It's tricky to just go half inch once the bit gets through the metal.
WHOA! :eek_surprise: HOLD ON THAR!!
I drilled the roof of my Frontier for an OEM roof rack and there's only one layer. I would be surprised if the Titan was any different.
The safest way would be to drop the headliner out so you can determine where you can poke holes without doing any damage to internals. I'm sure there is a thread of how to on here somewhere. Mostly just removing grab handles, sun visors, overhead bins/lights and the odd bolt cover trim piece.
A little research can save a lot of headaches :wink:
You can probably route wiring under the A pillar cover, you're gonna remove the grab handle anyway, and behind the dash to a grommet in the firewall.
