I,ve been told aluminum does not like treated wood.
Aluminum HATES dissimilar metals. It creates a battery that will eat thru it very quickly. I've heard of stories where people have dropped a coin in the bilge of an aluminum boat and it literally ate a coin size hole in the bottom.
Treated wood uses metals in the treatment, which can create a similar effect.
Assuming the aluminum is isolated, it's a very good material that will last a very long time. The biggest issue is the airstream style RVs are so expensive, you could replaces them 3 times over and still come out better financially.
