Drake, This is a HUGE problem. If you want a real earful, talk to John Wiles, Bill Brooks, or Greg Ball about this.
While you might think that the anodizing on the aluminum would prevent electrical contact to the copper, it doesn't last long with just a little vibration (usually due to wind). Put this in a coastal environment, and things go bad in a hurry, often in less than one year. Any island environment is especially bad. See ya!

How much of a problem is this going to create in the long run?

But this simplified chart boils it down. Stainless Steel (there are many grades) is generally very compatible with aluminum. Copper and Aluminum. . . look out. See ya!
