After taking a week off to refresh myself I woke yesterday morning with a solution to a problem that has vexed me since I started this project. Namely the door and the ladder to nowhere. I have always thought the door was a personnel portal when the titan was docked in the hangar for maintenance and maybe it served a secondary function as an escape hatch in battle but the ladder always looked ridiculous and wasn't needed. Scratch one ladder.
The other big problem was the placement of the door on the epic and DS model which seems too high for convenient exit. I felt that the logical place to have it was for the command deck people. The waist block has a hatch at the bottom and engineering exits through the catwalks under the carapace. That leaves the command deck and the reactor/void generator decks to vacate. Naturally descending on a ladder is too slow so in the vestibular immediate proximity of the door will be descent bungees for rapid evacuation.
One can assume when the titan is docked the door provides egress for the crew much as the gantry catwalk for the lamented Space Shuttle missions.
I did an major revamping of the command deck to accommodate this door and passage and there was sufficient room under the carapace for the vestibule.

Problem solved and in a logical (TMM) manner; Whew!

Regarding the cooling modules on the stern panel they are just tacked in place so I can get a feel for how they will look. They're not permanently mounted.
Naturally there will be a lot of piping and mysterious components galore to 'tech up' the exterior.
