Most reliable cold weather pellet grill?

Howdy fellas, I’m up in the great white north and temps get pretty chilly out here. -20c is pretty common for most of the winter. I’m on the hunt for a grill that can handle the extreme cold, and won’t crap out on me. I’m happy to pay for good quality, but everything I’ve tried (Grilla, traeger etc) have all failed me in the cold. Usually it’s the computer but everything feels cheap and made in china now. Any useful help would be appreciated! Thanks boys!
