I ran the 3300 and I'm running low on space trying to do 3-5 days out of it. Food goes in meat shelf or between lid as some were saying. Just my essentials and puffy/jacket max it out. I added the lid which kind of didn't do as much as I wanted. Definitely go for the bigger pack. There's no weight penalty (maybe some oz?) but you don't have to stretch the seams.
