Low range does help in certain circumstances but not necessary.
The Outback's approach and departure angles are not in it's favour... They have quite a bit of overhang which will cause you to bottom out regularly.
I used to own an MY02 Outback and took it on a few small offroading adventures. It performed brilliantly but it's no LandCruiser/Prado/Pathfinder, etc.
I took this video when a few mates and I went for a mini adventure. Three Outbacks and a Foz.
