Hi Greg,
We was to your place for a visit just about this time last year, but you weren't home. I love your province, I didn't realize the Rock was as big as it is. Like everything else so much to see so little time. I want to go back for six to nine months and do NL justice.
I would give westends solution a try. If you can take the hinges off and let them soak in a penetrating bath for a few days they will probably free up. The hinges are a pain in the backside to keep lubed up, I keep a can of silicone spray in the trailer and give the hinges a shot every few weeks. You can find the silicone spray at Canadian Tire.
