Be warned, this question contains some major spoilers for the later chapters and the epilogue.
In the epilogue you continue playing as John Marston instead of Arthur Morgan. That means you also lose all the stuff you collected as Arthur and start with a very empty inventory. And while I got Arthur's weapons back at some point in the epilogue, I don't have much money right now at the start of the second part of the epilogue and almost no food for me or my horse.
Can I get any of Arthur's money, provisions and ingredients back during the epilogue? Or do I have to start hunting again to be able to feed myself and my horse?
I'd appreciate if any story spoilers are tagged as such for anything later than the point of the story I'm at.
