Drive it and enjoy it. Dont rush to get all the gear asap.
I did that on my 80 series. So now that I got my 570 I have learned to keep it simple. When I started gearing up my 80 I went with roof rack and RTT. Front bumper. Rear bumper.. swingout. Lift 35s etc etc etc. After adding shelves.. removing them.. adding drawers removing those.. I settled on some slee drawers I got second hand here on mUd. Went from a 80 to a 63 to 30 qt fridge. Still have the 63. I started moto camping on my Africa twin. That really got my to lighten my kit. Not quite backpacking style where you count ounces, but looking for compact lightweight items and keep bare minimum.
Now on my 570 I use all the motocamping kit. So I can have everything im the back. I have the 30qt fridge and the 63 can replace that if it is a looong trip. No roof rack. If I need to bring my Oztent or Gazelle tent because it is a bigger group I can just strap those on the roof. Awning would be nice but I am on the fence on adding weight up high and getting extra wind noise. I might add a little mesh shelf inside the back om the third row. I have one for my 80. It can be removed but allows for some vertical organization.
As far as tires, i plan on keeping it mild so that I have no need for a rear swingout. BUT i do like a rear swingout because it gives you a place for a trasharoo or other such bag...
I'm not much into drinking the overland Koolaid much now. I would rather save the money for fuel and beer so I can get out more.
