Tarptent Hogback good for Mt Whitney Trail Camp?

I'm planning on hiking Mt Whitney this year with my wife and one or two other guys. We'll be staying overnight at Trail Camp. My wife sleeps better with me in the tent so I won't be taking my tarptent moment. The only other tent I have is the tarptent hogback. We two certainly would have enough space in it. The other two have their own tent.

The six tie down strings would need to be wrapped around/under rocks but I'm not sure if that will hold up to the winds that we might encounter up there. Also, how is the space requirement of this tent compared to others? Will we have enough flat space to set it up?

Any comments on the usability of the hogback at the Trail Camp is appreciated. It would be nice not having to buy another tent.

I don't know how windy it gets up there but if you do end up using the Hogback here are some suggestions.
First you can get an optional pole from TT , as you can see in this photo :

Note how the tent is set up.
So make sure that it is set up nice and taut, tents don't perform well when floppy.
(exactly like a sail but ,for some unknown to me reason, sailors don't blame the sails, campers blame their tents...)
Next, the 8" Easton according to BPL tests have a
holding power of 66lbs, so that is a combined power of almost 400lbs.
(the TripTease cord can hold about 250lbs..)
So don't be afraid to pile up a lot of weight over those corner guyouts as well as extending the ones in the middle so that you can wrap them around logs/rocks.
Lastly do install pole guylines ( so you have another two anchoring points)
Those should be used in all but the mildest conditions.
BTW, make sure the rocks you put on top of the PitchLock corners don't rub against the TripTease cords.

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.

This is why the Pitch Lock corner (Scarps/Hogback/moment and Notch) works well without stakes :

(I was seam sealing a Scarp this morning so I took this shot...)

Wandering Dasy, I don't think my wife would appreciate to sleep under the vestibule with her feet sticking out. Both of us would like to have a chance of a good night sleep. Using the Moment would guarantee that at least one of us doesn't have a chance. Most likely both.

Looking at the dimension of other two person tents (e.g. Big Agnes Fly Creek / Copper Spur, TT Rainbow / Scrap 2) they don't any smaller than the Hogback especially with rain flies.

I did set up the Hogback several times in the basement with dumbbells for cleaning and drying. So I know it's possible. Luckily there should be enough large rocks so that I don't have to carry the dumbbells.

This doesn't make sense to me. You're not proposing something asides putting the rocks on top of the guylines or wrapping the guylines around rocks? Maybe it's just that I don't know the terminology of PitchLock and TripTease.

"This doesn't make sense to me"

That is why I posted that picture so that you could see what I meant about rocks on the PitchLock ( the two CarbonFiber struts (black inside the sleeve) and the TripTease (yellow guyline) combination form the Pitch Lock corner)
If you have rocks with jugged edges there ,the wind can cause the guyline to rub and eventually break.
So make sure you either have rocks with a smooth surface there (not like my bricks...) or put something in between to protect the guylines ( cloth /stuffsack/spare socks if you have to...)

Got it.

Another question. Would you leave the tent up and slightly open with your stuff inside it so the critters can inspect it and hopefully not harm anything. Or would to pack the tent away and store everything but food in a tightly packed backpack that you leave at the camp while summiting? I read that the critters at Trail Camp are quite unforgiving with their search for food and made holes in closed tents. There are no trees to hang a pack.

I never had to worry about that since my prior hikes always had a different overnight location.

I've been to Trail Camp on Whitney a number of times and I would agree with your approach, leave things open for the marmots to check out while you summit.

If you leave your tent open for the marmots to check out and your backpack is inside, you may end up with chewed up straps. Marmots go for anything with salt. Hang anything with salt from sweat from a overhanging rock so they cannot get it. Better yet, take a backpack that you can also use as a summit pack leaving no chance for the marmots to get it.
