skiboats,

If this proves to be a good reasonably long-lasting solution, you are going to be a hero to many on this site. That's a great recommendation from your dealer.

Since my first freeze-up episode, I've been spraying a bit of Jig-a-Loo lubricant spray at the door handle and latch area once a week. I just lift up the door handle and shoot it into the two openings. So far I haven't frozen up any more, but that's probably because it's only been cold, not cold AND wet. The true test is when it's both cold and snowy/wet outside. I will definitely take your recommendation and spray a bit of antifreeze in there, it certainly can't hurt.
