Looks like your tt has a frig roof vent. Skip the drilling completely. Up through the wire mesh, out under the vent cover. Remove on roof vent screw. Make a simple met bracket for that location. Put the screw back in. Should attached to a good reinforced location.
No new holes. No new decor location to maintain.
