propably for triniun knowledge socked expanse it just need bigger size and to add more cargo holds on sides (copy paste it in free slots)
its very slow but i use those kind of ships as mobile cargo holds for my miners and i tend to mine alot raw ores before refining so mobility is not important
do not mind inside, i build those ships to look nice on outside mostly. Had to use framework because size and weight required more thrusters that would mean less cargo hold
