Perfect! Thank you Cmdr!
Was just booting up to sell my Conda for a T10 and use it as a trader anyway.
The only "problem" with using a T10 as a trade-ship is that you'll have to make the conscious decision to not get into any combat with it because, if you do, you'll start down the spiral of upgrades/compromises that'll end with realising you should be flying an Annie instead.
Course, it's on you to make that decision and stick to it.
I tried to do the same thing with my Cutter.
I D-rated everything, fitted the smallest possible PP, installed puny little weapons and a modest shield with the intention that I'd see off any small attackers and just run away from anything larger.
Trouble is, the game spawns opponents depending on your ship and, as a result, it's always things like Annies and Clippers which come after you and you have no choice other than running away - which isn't fun.
In the end, I just relented, picked out some decent weapons, upgraded modules to support them, spending a heap of credits in the process, and now I've got a ship that still fulfills it's primary role as a cargo ship but it's also got the teeth to defend itself when required.
Which is where you'll run into problems with the T10.
Because it's so big, and heavy, the only shield that's reliable for combat is a C8 (or, presumably, a C7 prismatic) supported by a bunch of boosters and that's going to cut into your cargo space, require that you fit a C8 PP and cost a heap of credits.
It doesn't have to be a problem, of course. If you're determined to avoid combat completely, you'll be fine.
Also, on the bright side, my T10 is currently armored up the wazoo and fitted with all the guns and it's still capable of 25Ly jumps, which is a distance my Corvette could only dream of achieving.
Right now, I'd still prefer to take my 'vette into combat because it's more agile and it's got weapons that I can rely on to get the job done.
If I can find a similarly useful weapons loadout for the T10, though, it won't be easy to decide which is more useful.
And, if the combat requires travel to get there, the T10 might even be the ship of choice.
