Depending on when you arrive at trail camp, the large tent sites may be all taken, leaving some tighter spots. As a rule of thumb, at crowded Sierra sites, the smaller your tent "footprint" the better. Generally, the weather is good and many people just cowboy camp. I have a Moment and in a pinch two people (depending on their size) could fit inside. How about your wife inside and your head under the vestibule with feet outside? You would be real close, albeit not exactly inside the tent with her. It rarely rains all night. During brief thunderstorms you could both cozily squeeze inside. If you decide to take the Hogback, part of the floor space may have to be set up over rocks, lumps or steeper sloping ground.
