off-road with double doors; 3.4L V6.

Help me here, it's been a LONG time since I've had a new Toyota, traded our '85 Toyota SR5 for this last night.

I know the obvious items, i.e. power doors, locks, daytime running lights, etc. But what I don't know, is, is this particular auto the 5-speed with overdrive?

Also, there's a powermode button - surely it's not the same as my Isuzu's, can someone explain when to use and NOT to use this feature?

What's the difference between the Off-road package and towing package?

And, can someone tell me for certainty if the LT265/75 R16 Yokohama tires will for sure fit this rig?

It came with whimpy highway tires in the 265/70 size.

What options come with the TRD Off-road? I know there are upgraded shocks, extra skid-plates, but what else?

Thanks!

Oh, and we got $1,750 for our 21yr old Toyota with 260k miles on trade in - can't complain, considering it was literally a bucket of rust.
