Years ago when I was still in the Air Force (Corrosion Control) we found a
table of the galvanic differences between various materials. I recall that the
difference between mild steel and aluminum was minimal whereas between mild
steel and stainless steel was significant. Sort of turned our pre-conceived
notions inside out. We would on occaision repair vehicles other than
airplanes, and since aluminum was readily available, it found its way in to a
lot of cars, trucks and snowmobiles. I didn't stay in long enough to see any
long term results.

Subj: [Shop-talk] Rivet Steel to Aluminum

We need to attach powder-coated steel to the outside of a painted
aluminum truck body. I don't want to set up a galvanic reaction and I've
never pop riveted anything into aluminum.
-How do we prevent galvanic corrosion?
-Are there special pop-rivets or tools for putting rivet into aluminum?
The truck body is held together with some large diameter rivets, but I
am guessing they had two-sided access when they assembled it. We only
have access from one side.
