There really isn't anything of real note. A few very very minor things but I wouldn't call it drama.
Mike and Jay had a feud decades ago, before RLM, with a few funny details including forum sockpuppeting, drunken declarations of love to a girl, and profuse vomiting. Rich's parents were drug addicts so he was raised by his nan, and it's one of the reasons he doesn't touch booze etc. Those are some very old interesting factoids that might count as drama once upon a time?
They unlisted the Max Landis episode of BOTW after he was metood for the dozenth time. Jim, the canadian, is an insane leftist on twitter and beardfat isn't much better. Jack Packard announced he was one year sober recently, claiming that he was a long time alcoholic.
Reality is that they are all very private people that don't get particularly involved in other online personalities' business. They make their youtube videos, keep most of their fan communication locked down to their patreon (and even then it's sparse), and are seemingly quite content to just keep doing what they're doing.
