Thinking about being a space trucker in the game.

Hey so after years of hiatus and completely missing out on the Thargoid arc, I was thinking about setting up my Saitek X52 again and doing some chill space trucker adventures until I get bored of it or hopefully not.

Here is my commander info: https://inara.cz/elite/cmdr/38435/

I have like 320M in credits and 3 ships, one of them the Krait Mk2 which I've done a lot of mining with.

Give me some pointers about becoming a space trucker. What are the resources I can use outside of Inara and EDMC? What is the de-facto "space truck" to haul cargo with? Or if I don't have enough creds for such a ship, I just want a robust hauling ship I can use to make decent cargo runs with.

Maybe one that's also good for occasional illegal goods smuggling (I've done a few heat signature concealing runs for criminal passengers, that was fun).
