Here's the skinny on the 4Runners. They are mechanically very similar from 2005 to current. They all pack the 1GR-FE or some variant of, and the A750F. You should be familiar, as it's the same drive train as your Taco. The 2010 brought the current facelift and nicer black headliner. Prior to that they had the two tone black/gray interior.
One thing to consider is the 2003-2009 4Runner that was equipped with the 2UZ-FE V8. That's a whole can of worms by itself.
The Trail became the TRD Off Road. The Pro added more appearance stuff (such as unique color every model year), and nicer shocks. Pros didn't have available moon roof until 2019. There's a bunch of hotly debated issues like KDSS vs non-KDSS.
Bottom line, sell the TRD Access private party or Carmax (I'm guessing you want more room), and find a TRD/Trail 4Runner you can live with. You wont' be disapponted.
