Has anyone ever tried this? Harpoon+cart?

I’ve heard you can drag more weight with the harpoon. So for instance, pulling a cart uphill is hard and drains stamina, but pulling your buddy fully loaded basically ignores that weight.

Here’s my thought:

Load a cart full of iron, have 3 friends load up with iron, over encumbered, and sit in the cart.

Have one buddy not encumbered in position to pull the cart, some iron in inventory ok.

Finally, the last guy harpoons the friend who is supposed to pull the cart. This person drags everyone as if the cart was empty bc the harpoon ignores weight.

The guy who is in position to pull the cart still walks along and steers the cart but it’s all ran off the speed and stamina of the harpoon guy.

Thoughts? I just thought of this and I can’t play till next week with ppl to test.
