Not exactly same scenario, but my 80 is pretty much done, and we have a 5 year old 4runner limited. We put the 17X7.5 toyota wheels on the 4runner immediately. In ground clearance, maneuvering, acceleration, gas mileage the 4 runner wins. We have had some minor issues with the runner that were easily addressed and overall the lower maintenance schedule in comparison to the 80 is another +. I've been debating getting another 4 runner to finally get rid of the 80, and can't find the right combination that makes me say "yeah that's the one". Atrac may work, but I prefer full time AWD, real lockers and the option of running an open center diff in low range.
