The cargo hold could carry anything. I just used shipping containers to show scale (using something familiar). The entire cargo hold would be a sort of "pod" that you could fill with whatever you like. Different "pods" could be designed to carry anything. Just trying to come up with a docking system that would be universal to all "pods".

There's a freight elevator for other parts of the ship (non-cargo). Gasbags could be loaded that way if necessary. I was also wondering if you could flood the cargo hold with helium/hydrogen to displace any air in the cargo hold and provide extra lift. Though it would probably kill any live cargo in the cargo hold.

Which is another option... If your cargo needs life support, the cargo hold would have to be designed to provide it. The different designs of cargo holds are endless. I was just trying to figure out how they would all be lifted by the Precariat.

Came up with another style of "cargo" that uses the Precariat as an air launch system for satellites.

There are a total of 52 launch tubes to launch several types of payloads. The Precariat would lift to 100km, then each tube could launch it's own stage 2 rocket to take it's payload to it's final altitude & orbit.

There are 33 small (5' dia. / 72' long) launch tubes for rockets with smaller cube-sat style payloads like Vector-R/H & Falcon 1.
16 medium (17' dia. / 72' long) launch tubes for Falcon 9 style payloads. And 3 large (26' dia. / 448' long) launch tubes for something much larger.

Rockets would be launched from the "cargo hold" with cold-gas thrusters, then ignite their main thrusters once clear of the ship.

The Precariat replaces the conventional stage 1 of a rocket launch system. The rockets that launch from the ship only need enough power to achieve orbital velocity and lift the payload to it's final altitude.

Was going to make an animation to show the process, but it will take forever (please donate!).

Uploaded both cargo designs to Sketchfab so you can view, rotate, zoom & explore the model in your browser.
