I took my four-man to Alaska and it worked great.
However, I brought it back to Idaho and it was crushed and completely destroyed by heavy, wet snow. The snow broke the poles which straightened out as they snapped and thus ripped the tent wide open.
I had the set the tent up a few days before, then returned to town and hiked in again for a long weekend of the late mule deer season. After a two-hour hike I arrived at the tent at 11 p.m., it was no where to be seen. I had to dig it out of the snow, as it was flattened.
Still, I propped it open enough to crawl into and spent the night in a feeezing wet sleeping bag. When I awoke before dawn, the wet felt liners (had to cross the creek a few times the night before) of my Schnees pack boots had frozen solid, but not in the shape of my feet. Took me forever just to get my feet into them, and about 20 minutes of hiking straight up a ridge until they melted enough to fit my feet.
I arrowed a nice buck about an hour later.
Moral of the story-----unless the poles of the larger Alaskan Guide tents are thicker and stronger than the four-man version, If the snow gets heavy you may spend some cold nights in a collapsed tent.
