Thanks for the input. All-season usability is a big part of the reason I was leaning Duoumid. With a bug net, it could replace my Rainbow when I want an enclosed shelter, for 8 oz less weight.
(My Rainbow is an older model w/o the pole grommets to support the arch, so I'd have to MYOG my own.)
My experience in the Sierras last year with a BD Megamid tells me it should be doable. We slept 3 in it, and dug about a 4' deep hole to put it over, digging into the walls to make it more spacious.
I don't mind so much getting up to dig out. Had to do that in the snowcave as well as the door was getting blocked up with drifts. And I have to say, standing outside in a white-out at 3am, in the mountains, all alone, is one of my favorite experiences ever.
I just got concerned when I read in a G-Spot thread about Ryan Jordan having issues with Duomid snow-loading, since I assume he knows what he's doing.
I'm new to the East coast, having moved the NYC from San Francisco in August. We ditched the car, so I'm still figuring out where I can go car-less camping from the Manhattan. Any tips would be appreciated.
