I would love to see a mod that adds a non-ride-able pack horse or donkey loaded with bags.
Give that animal the OP carry capacity and change the war horse you ride into something reasonable.
Some of you modelers like Promethius_ts, Hothtrooper, or Insanity (not meaning to leave anyone out).
Wood work perfectly for those who don't don't want to ride horses, but want an immersive way to carry more loot, tents, supplies, etc.
Also useful as a modder's resource, for caravans, and for other adventurer parties.
