Bought an Aluma 7712H, but want to use wheel bonnets with it. It look like having the tie-downs in-line with the tire centerline is the way to go. I thought about an aluminum track system from Mac, but $$$.

Anywho, I was concerned with putting recessed steel/zinc tie downs against the aluminum deck and getting corrosion from dissimilar metals. Had anyone done this? Does it matter? Are there alum. options? The only other thing I could think of was using some RTV gasket maker gunk between the plate/backing plate and the trailer deck?

Thanks All
