Welcome Josh!
I have the same model, same year, no mods. They go pretty much anywhere stock. This one's been up to Cameron Corner, Innamincka, Birdsville & up big red, Dowling Track, Birdsville Track, Nathan River Road, Lorella Springs, Hells Gate, Flinders Ranges numerous times, Arkaroola.........
I had a 2010 Stockie before this one & it did the Gibb River Road, Bungle Bungles, Oodnadatta Track, Mt. Dare, Dalhousie, Lambert's Centre, Old Ghan Track, Chamber's Pillar, Mereenie Loop, Gawler Ranges, Kangaroo Island, the Old Jim Jim Rd in Kakadu, and the Flinders Ranges numerous times in that one too!
My wife has a Pajero, which is more roomy & comfortable, but I prefer the D22 out on the tracks.
