Currently, my 90 lb weakling, half starved recruit can physically pick up and throw over one scrawny shoulder a pack mule shek carrying about half again his body weight in ore. While this makes the recruit look awesome, it also makes my brain go "whuh?"

A possible solution, the travois. Or basically, two sticks and some rags holding them together. There's already ragdoll physics. And beds. Create the travois, put the char in it (like a bed), dag s l o w l y back to base. And get mobbed by every bone dog, beak thing, and berserker in a half league radius on the way back, but this is Kenshi.

Granted, it's only a nice-to-have. But it would add quite a bit of depth.

double it with the ability to load items on it and you have a great hand pulled cart.
But it should severely slow the character down and also should be dropped when combat starts.
