I was contemplating this a while ago, the Revo is a nice rig, I seriously thought about trading into one, I would highly recomend test driving one before you do anything, also be aware of the reduced payload and useable space, or talk to the guys that have had both, and get their feedback on changing rigs...just a thought
In the end I kept the Outback...but if you do decide to trade out let me know I would be interested in you '10
