This is a vertical interpretation of the Type A2 chassis, though with no components installed so far.  This was originally posted to the G+ Traveller community as a design derby frame, since a couple people had agitated for vertical hulls. No one bit when actually given a working frame...

A participant on the Mongoose boards posted a hand-drawn re-arrangement of the A2, so I modified my version as well.

Aside from adjusting the vertical hatches so they line up and adding airlocks to his external iris valves and the cargo access, this is FraNe91's layout.
