This started as more of an amusing thought than a serious suggestion but, why not?

Processing, on horseback. You can expand on this in a number of ways but we'll stick to processing for now.

Why? Why not? For those tedious horseback journies when you just have to "be there", you want to take in the scenery but have a sense of fufillment within a multi-tasking framework.

You could limit it to, for viability, two-seater horses only. No friends to snuggle up to for that cozy jounrey? Don't worry, when you can't go broke-back mountain you can still get a sense of fufillment by using that empty seat as a processing spot, shaking has never come so naturally. Your horse may have health and safety concenrs over heating and cooking so we could draw a line there but we can still dry some fish.

actually i would rather see our storage chests in our houses work with the venecil costume

but your idea has merit expecially if we could use the horses weight/inventory as part of the processing capabilities.
