thats a pretty cool setup.
ours is fairly similar, just missing the long range tank.
plus ours is a rubicon, so most of those things came with it, plus a few extras
xenon flares... i thought i was going need them, but the tyres only JUST stick out past the stock flares, and if you're running the mud flaps front and rear, when looking from the rear of the vehicle (which the the end that stones get flicked out of, they cover the tyres fine (ive got MT Baja Claws 315/75/16's on 16" ProComps with 4.25" BS). So, you might be able to save yourself a grand there if you dont need them.
we got the original rubicon rocks rails, and they've been great (have taken quite a few hits that would have otherwise been a trip to the panel beaters). mopar have since released another version of them with extra tubing along the side, that would be good to have to help get in, especially now its been lifted
Are you getting the ARB winch bar, or just their rock bar?
I'd suggest the winch bar even if putting a winch in now isnt in your plans. Given all the gear you're getting now, its probably going to be something you'll want one day.
The only other thing that came to mind was maybe the Off Road Group (i think its called that) package with the factory rear locker and sway bar disconnect a better option than the ARB Airlocker - i've got no idea of the prices of these btw, it was just a thought.
You must be excited
Looking forward to seeing it when its all done!
