I have several panels where the aluminium has started to corrode and is breaking through the paint, also, the tailgate is made out of metal and it will start to rust there. Mine rusts just below the window seal/cover strip and along the bottom where the two pieces of sheet metal that make up the in- and out-side are pressed and folded together. I would certainly take care of protecting that to prevent it from rusting. Other than that, the chassis is remarkably well protected and seems to not be very prone to rusting, even in a wet and salty environment but again, eventually they do rust :)
