I saw someone else say this, but having a way to secure your cargo would be nice. Maybe at a later station you could get a toe strap upgrade that lets you tie down your cargo to reduce your chances of having something fly out of the back when scaling hills or mountains. The obvious trade off would be that putting scrap into your tank while between settlements would be difficult because you'd have to undo the straps and pack in the new stuff before tying everything down again.
