I always haul massive amounts of cargo with a Type-9, and I don't have much problems. Sure, I sometimes bump into a wall or (more often) with the landing pad, but that's just minor damage easily repairable at that very landing pad. If you find yourself constantly destroying your ship against station walls, maybe learn to fly, no offense intended...
Btw, engineer the lightweight hull for 'heavy duty'. It has literally zero drawbacks (it doesn't increase weight) and will make it more resistant to damage.
