I've got a 6x12' enclosed aluminum trailer and want to mount a couple of aluminum cabinets in it high on the wall. I assume this is generally done using self-tapping stainless steel screws through the back of the cabinet into the aluminum wall studs.
I was concerned about the dissimilar metals causing corrosion but from what I've read the stainless steel screws should be fine since it's not in the weather.
I'm also concerned that it might not be strong enough and fall right off the wall as I travel across the country. I don't plan to put anything especially heavy in the cabinets, but I want to make sure they are secure. Are self tapping screws sufficient for this?
