We had several corrugated aluminum RV's. All leaked because of the undulating shape of the siding. It was impossible to stay ahead of the water intrusion, rot and mold. Had to take one of them straight to the dump.
What? Aluminum siding is not more susceptible to leaking than any other type of siding material. Water would have to go down the siding, back up the backside, down the joint and then back up again to reach behind the siding. That is some magical water!
I think perhaps your issue was water getting in some other way...
OP, I have aluminum because it is cheaper, lighter and easier to repair than fiberglass. Moisture behind fiberglass walls will cause delamination which is very expensive to repair. Moisture behind aluminum can be remedied by removing the aluminum panel, repairing damage and replacing aluminum panel.
