That kind of use over such a short period of time should be proof enough of reliability.20k miles but for how long? Lol
Can’t really talk about reliability in such a short time frame of around a year or so. Maybe in a few years, we can revisit the conversation.
It’s like eating a bag of cheetos daily for 6 months and say your completely healthy. Keep eating it and after 5 years, then see how you are. Lol
Bottom line, if you're afraid to do anything for fear of breaking shit, don't modify it. Or maybe even consider a different platform.
