Several others have recommended Outpost > Trail. I'm seriously considering it. My hesitation is the desire to get as many miles in as I can on the first 'easy' day, so I have less to do the summit day. It seems some of the harder climbing is directly after Outpost--and I can understand how it'd be nice to not have my giant heavy backpack for that. I just don't want to regret it on the morning I wake up to summit and now have 2 more extra miles than I could have. What do you think?
Not having camped at Trail Camp before, here are my thoughts on Outpost Camp: it was very comfortable with shade and good privacy for when you need to pee etc. Very relaxing spending the afternoon there before getting to bed early, trying to get a bit of sleep, and waking up early to hike to the summit. On the way back down, Trail Camp was baking and it was nice having some shade at Outpost Camp while breaking down my tent. While Trail Camp has some otherworldly scenery, it seems more exposed to wind and weather, but you would be closer to the summit, and there would be less pressure to start earlier. I like Steve C's idea of playing it by ear once you get there. You should be feeling pretty good after spending 3 nights at altitude and having done one or two light warm up hikes at higher elevation.
