I have one.... access cab, auto, v-6. It's great. Gets 21 MPG in mixed city / highway driving. Handles great. Plenty of power (in fact compared to my `94, this is a rocket ship).
I use mid-octane Shell and it seems to run just fine. I don't tow with it and the 4-wheel use is just on the road. It's an SR5 not a TRD or off-road.
I love the seats and there's decent room in the back for short trips. The extra doors are great for loading and loading "stuff".
All in all I'm very happy with it.
