The Lucky Break's Shuttle!

Here's the shuttle for the Lucky Break. No name, no permanent crew! It's an a-grav only vessel, so only works in orbit or surface to orbit. The seating below and above, and the the inter-deck flooring between, can contract into small but dense cubes and be offloaded into the cargo deck. Changeout is rapid and simple. You would have three configurations - 30 passengers on two decks, 15 passengers on the upper deck plus cargo on the lower deck, and full volume used for cargo. Normally, you would use the Breakout for cargo lifting and the shuttle for passengers, but if the Breakout is detached somewhere else, you could use the shuttle for both.
