What's your Suggested yearly Maintenance/Repair fund/budget?

So I read/heard: Make sure to have money saved for regular maintenance and unexpected repairs. Anyone care to share or advise or suggest what they set aside (or what to set aside)
or keep aside for the above events?
* I understand some have Diesels some have Gassers, some have Luxury class A's some have Entry level and mid level. Pls don't make it to complicated and overthink the question. I'd be happy if you can just distinguish between Diesel and Gasser and throw out a ball park figure. That's doable right? Lol. Like always, thanks for sharing.
