Don't know about high-level discussion, but the only other active forum I frequent other than Reddit is https://www.tacomaworld.com/. Really active user base and a ton of good info about different generations of the Toyota Tacoma.

Car forums are really popular and somehow seem to survive the tests of time. For example, Rennlist has been around for decades now.

That forum was a godsend and really supportive when I converted my prerunner to 4wd!
