Bracket mounting propane disconnect to trailer came off

Mine came loose too last winter while in Fl. I went to a local hardware store and picked up some oversize screws ( little bigger than original ) and a small tube of adhesive caulk. Used a liberal amount of adhesive caulk and let it dry for 24 hours before we moved. Thought it might be a temp fix but it lasted the rest of the trip and our trips so far this year. I plan on leaving it alone unless it shakes loose again.
