John, I appreciated your report from last year, especially the video. I referred Newclimber in Australia to it. The view of the person glissading, and of your hiking partners climbing really give a good flavor of that section.
As for your hike in November: Sure is late in the year, will be cold. Also remember: way more hours of darkness than in June.
Comments on your plans: It will probably take you more than your planned 5 hours to reach Trail Camp. Also, daylight savings time ends on Nov 1, so it will be nearly dark by 5 PM. Your packs will be heavier than a summer trip due to the extra clothing required for the cold. You might consider camping at Outpost Camp for a more hospitable location. Get up earlier there and you can still make the summit.
For warmth, 2 and 4 people in the same tent keep it warmer, so the 20 degree bags should be ok. You may need to sleep in some of your clothing.
Last water should be the inlet to the Trail Camp pond. There will be water running into it. You may need to break some ice to get to it. If you have an ice axe that should work.
Bears won't visit Trail Camp, but the marmots will. I have heard people hang their food over a rock using a stuff sack to keep the mice and marmots out. (But the bear can is required.)
Looking at the satellite view of
Trail Camp, I think the sites south of the trail are big enough for your 4-person tents.
