Here's what I did. In Minnesota. Similar door on other end. The sliding hardware can be used with some lumber spacing on the inside to position the rail. I couldn't find any latching that would work on the inside so I had to rig up some turnbuckles. I wasn't really satisfied with that. Those doors do take up most of the end walls. You could build a fake end wall if you wanted the end wall space, I didn't.
It worked just like I hoped. I did a little snow shoveling at the edges but otherwise I opened the door and drove the snow loader tractor out the door and started pushing snow. And I didn't have snow drifts all across the end to shovel just to open the door.
Another benefit was that the rail hardware has no rust after 25+ years.
