We've done quite a lot of touring (Kimberley, Fraser, Red Centre etc.) as well as a lot of serious offroading (JamieOGilmore's Channel - YouTube
We've done all of that without the long range tank or swing away wheel carriers (I just think they look terrible on the RRS).
While there is very limited room in the RRS for storage, there are some easy ways to get around it. Also depends on whether you are towing an off-road camper of course.
Here's the list of things we've bolted to the sport
LR Winch (requires cutting of front bumper to install)
Front bash plate
LR Air Intake (Modified install to full snorkel capabilities)
GME UHF (use hidden head unit under steering column cover to minimise impact)
Rhino Racks with expedition cage (lighter system than most others)
Elec brake controller (essential if you're going to be towing long distances offroad) + anderson charge plug at rear
Dual Battery (Optima with redarc isolator fits well)
Rear LED interior light bar (rear light in RRS is mounted too low and not useable with gear packed in boot)
ARB fridge and slide (Note: you need to modify access for spare if you mount a slide in as you can no longer raise the rear storage flap)
Dog Guard with shovel and mattock mounted (essential if you want to pack a bit of gear in boot)
ARB awning
Twin 6000 lumens LED spotlights (RRS high beams are rubbish)
ECU upgrade for more power/economy
LLams offroad height controller (we found this invaluable for a lot of offroad touring)
Mitch Bros offroad hitch (only required if you'll be towing)
17inch steel rims with muddies (definitely order a set of 18's)
We mounted the extra spare tyre on the roof and put a space case up there for extra storage
Make sure you also order the new sport with the E-Diff option as it can't be retro fitted. It makes a huge difference in offroad ability and is great value.
Cheers
