Mine were some standalone Blue Ox towbar locks (look kinda like a dog-bone), and the Master locks were for various hasps, etc, like on tool boxes and such. All were caught in the 6-8 ft surge, and then sat in the water in the shed for an extended time after they got knocked off the shelves.
Didn't know about Tri-Flow when I tried to open the baggage doors, but they were also frozen-shut so it might not have helped from the outside. Irma had gotten right up to the 'beltline' of the Endeavor. Coach was a total loss anyways
On the 'new' Camelot, I've since gone around and pulled the inside cover off each baggage lock assembly and Tri-Flowed all moving parts. They were working before, but move so much smoother and easier now! Even the solenoids snap faster.
