On my way back to Wolf 363 after refueling in CEOS. It's been a strugle finding Tritium since I needed to refuel to be safe despite living Colonia with more than 5000 tons of it including a full fuel tank, I'd say you really need 6000 tons of Tritium to do the trip from Wolf 363 to Colonia.
Carriers needs options for upgrading and engineering. right now, they are just able to park somewhere after a short jump and are not really suited for exploration, I figured I use 114 tons of Tritium for <> 500 LY range and navigation is fiddly at best.
I use my Python fitted with maximum cargo capacity into which I transfer fuel and then donate to the carrier after each jump to fill up the tank, I also use the ship to calculate a 1000 LY route then follow its waypoints until I reach one as close as possible to the carrier 500 LY range.
Once I got this done, the problem is that it take a lot of time and manipulation for something that could be a lot simpler if the carrier had an option for engines, navigation and FSD upgrade and engineering.
