Privacy and space available. I believe giving each individual a space at least similar to a japanese capsule hotel will be very efficient. People will sleep there and they will spend a significant part of their day there. Freeing up communal space for the 1/3 that are out there at any given time.On submarines people sleep or they are on station. On transfer to Mars they won't havea stations to attend.
You can't sleep for 8 hours, then work for 16. Studies have shown that even 8 hour workdays are potentially less efficient over time than 6 hour ones, because the human brain has trouble focusing on tasks for so long. You're going to need to kill a lot of time one way or another, in a way that isn't too mentally taxing (i.e. not study or work).
I suspect that most of the initial colonists will be naturally inclined towards learning.
People will need a private space - I've seen mentioned that interpersonal conflicts are the highest stressor for both long duration space flight and antarctic overwintering. Sure, early pioneers managed all bunched together but remember that there are plenty of examples of even high functioning and stable people losing it and even killing each other (don't play chess ).
Trucks? Take it back to the LOX plant.Rent the LOX for the test; pay for any LOX used and transportation/handling/overhead costs to the LOX producer as negotiated as part of the deal; return the rest back into the supply system to be sold as LOX as usual; cleaned/refined if necessary.
It turned out that the ITS LOX tank has been built in this large building - former Pacific Marine Center.

Dazzling. There are trial components for a mars spaceship undergoing qualification testing (albeit, the final tank is going to be longer, still).I'm.... still processing that thought... give me a while....I wonder how much that tank swings. It's light and huge, the pictures don't truly reveal how huge - might be a bit of a sail in higher winds. I'm not foolhardy enough to be concerned that they'll actually drop the tank moving it from barge to shore however.
