Colliehauler, I apologize if that sounded like a jab.

Colliehauler, that Air Hawaii jets cabin did not fail due to corrosion, it failed due to the use of triangular rivets which after years of pressurization/depressurization leads to cracks in the aluminum skin.

Absolute NO NO!!!
If you go to the boat forums, you will find long discussions of how to isolate aluminum from stainless steel because it cause the aluminum to fail or how a DIY job turned ugly in just a couple years because the guy didn't understand this.
My 52 year old Columbia 8.7 had all SS rigging attached to anodized spars. When you drill a pilot hole, the inside is not anodized. Not one failure for probably a hundred or so screw or rivet points. Most of the couple hundred sailboats at the boat yard where I spent most of my growing up had the same.
Now, the Al in an RV isn’t the same as a boat. I have seen corroded and falling apart Al in various situations. Mainly from little or no maintenance. Electrolysis will eat Al fairly quickly if allowed to.
My original point was that Al is an excellent building material when properly maintained.

There are probably hundreds of thousands of aluminum spars on sailboats around the world existing in a marine environment. All aluminum hulls, too. With stainless steel fittings attached with SS screws. Some have brass and copper attached, also.
No building material lasts forever. But with proper maintenance, any of them will probably outlast you.
