G'Day,
We went the Outback Hawk for reason of the kids too. Here is my list of essentials
Replace all of your interior lights with these http://www.brightlightautoparts.com/files/UN12-20.pdf
Run a dual battery setup 2 x 100amp/hr is perfect.
Run 100amp cable from battery in car thru Anderson plug directly to the batterys in the trailer for on the go charging.
If you are going fixed solar, go much bigger than you think you need. If they are mobile like mine, you can gain a lot more amps by shifting the panels to follow the sun.
Add a volt meter so you can see the battery voltage
Add an electric inline pump and a push button switch for the water (The hand pump will drive you mad)
Drop Jacks are excellent
Longer draw bar is gold!
Bag flys are a must
A water level indicator is a must for the water tank (s) Add an extra tank if you go bush for long periods.
Boat rack is a good idea, we use ours a bit.
Make a pole carrier to save boot space.
INstall your own Stereo, it's easy and you can get a cheapy from Supacheap for bugger all that will do the job
Buy spare fridge control plastic covers as the kids will break at least one of these (not kidding
)
Protect the underbody with rubber flaps and stone guards if you are hitting gravel roads. Stone damage is crazy. Maybe check out rock tamers for your vehicle.
That list should keep ya busy for a while. These are all mods I have done to mine and it's almost perfect now.
Enjoy your camper, they rock!
