If someone can lift a lot, but can't carry it far, then they have the Strong Arms advantage. If someone can carry a lot but can't lift much, then they have the Weak limitation on their arms. Either way, lifting in GURPS is ultimately tied to your arms. If you have a heavy hiking backpack sitting on a table, but strapped to your back, when you lift it off the table you'll be lifting with your whole body, not your arms, and your body is stronger than your arms. Since you'e not lifting with your arms but your back you need to compare this to your Carry On Back rather than your Two-Handed Lift to see if you can lift it off the table.


There is also the Payload advantage, which is the advantage for increased carrying capacity. So really I don't see a need for something new. Just take Lifting Strength with a limitation for Not The Arms.
