Well, I have just brought a Type 6 Transport which comes with 50T cargo space as default, but I want to get it up to 100T.
Thing is I am a bit confused of how to do this.
I am currently at Mars High and here is my ship as default:

Thing is, I don't really know what those numbers mean at the end of each compartment box.
I went into outfitting and there was only one cargo space available at a measly 2T. Is this because that's all this station has to offer and so I have to go to another, or is it that it's all that my ship can have?
I have this that Colin the Grey kindly sent me:

But that seems to suggest I kit my ship out with more than it can handle. For example, in Colin's information screenshot above it shows several cargo compartments with a capacity of 32, but my Type 6 seems to be saying that it can only have 16 in each.
Please can somebody explain to me what I need to do to upgrade my T6 to as high a cargo as is possible, without losing shields.
Thank you.
