With the upcoming cargo refactor, and work on making the mass of cargo affect ship flight models, it looks like a rework of the Caterpillar internals may be planned\in progress.
Looking at a post by CIG staff on Spectrum (https://robertsspaceindustries.com/spectrum/community/SC/forum/3/thread/commodity-kiosk-feedback-show-commodities-not-ship/5162288), there were 2 images of the caterpillar included.
The second image was a simple line-art of the Caterpillar, with a large block in each compartment, which didn't provide much detail:
The first image, however, seems to suggest an intention to move the internal upper walkway to the centre-line and make walking through on either level possible once the ship is fully loaded:
If this does occur, it will be interesting to see if it is possible to move between levels via ladder in each of the compartments - there does appear to be a small gap between the cargo and wall in the second image, where a wall-mounted ladder may fit...
This may also affect the cargo capacity as well: The second image shows a capacity of 120 SCU per main compartment (one is highlighted in green), meaning the front would need to hold 96 SCU to contain the current capacity of the ship - The only image I could track down ( https://external-preview.redd.it/N4ehgn3Gp4TKepsphUeGNGKffT73V06QN6k2EcPaCBk.jpg?auto=webp&s=6386ee9fc171e098bd64b074b0f0acefc6ac490f ) on the caterpillar's load showed 124 SCU per main compartment and 80 for the front, although in theory the front cargo could be expanded to as much as 108 if widened to 6 stacks of 3 (if the image is accurate for how this ship is loaded now)... Perhaps decreased by 12 by removing 2 stacks of 3 from each side near\below the turret to retain curent capacity?
