We need a back pack that allows any item that can be picked up and carried to be equipped to the backpack slot.

could be an artifice for the backpack, "straps" or some **** that allows you to carry a canoe/sled etc while using a pack.

What is the point of building a canoe if you can just carry around your boat?

I think the OP means so that things like boulders, logs, chests etc can be "equipped". Trouble is I think this would allow teleporting with stuff which is a feature the devs removed didn't they?
