Considering that I have always heard that when dissimilar metals are in contact they start corroding, is this ever an issue with pillars since most I hear about are made out of aluminum?
That is a really great question and I hope someone actually versed in the beast will answer...
The way I have looked at it is that the aluminum is only barely touching the steel and for the most part there is a layer of oxides which precludes corrosion, especially in the absence of a full-time solution.

Also, I have been using these for many years in very salty, wet conditions and have never seen anything resembling a dielectric response in the bedding, but have seen it many other places?
