Aluminum is not immune to corrosion either. It can be worse than steel.

Aluminum + steel + salt + moisture = battery = galvanic corrosion.

If you install it incorrectly, this is true. Hopefully the OP will take the time to isolate the aluminum from the steel if they are installing it.

Just bolting it direct metal to metal is where galvanic corrosion comes into play.

Assuming it's installed correctly and price isn't significantly different, I would go aluminum. It will save weight and not be prone to corrosion.

be sure and ground the aluminum well with a good bond to the cab. Use all stainless mounting bolts. I recounted the years with my aluminum and it's actually almost 26 yrs now. Been on two different trucks. If it was steel it would look like 26 years are on it. It still looks good but, has scratches like your old pots and pans. no corrosion
