What cannons can be mounted on cargo carry?

[Lukaseka95 7]

I would like to mount some cannon or mortar on the cargo carry mounted by a bear. Is it possible? What can be build on that cargo saddle?

It used to be possible, I think they changed it in a recent patch so you can't put cannons or NPC on the cart now. As far as I know it's useless, I had originally made 1 thinking it could hold more weight, nope, not unless they recently changed that also but mine is in the cupboard

Lol Mortar. No you can't mount that. You can mount a medium cannon or a swivel gun.
