Trust me, you aren't going to have white corrosion everywhere. If that ever happens, it will be many, many years down the road.

16" or rain! That's more than double what we get! Our average is 7 inches per year. We did have one exceptionally wet year; 18" in 2006. Most in recorded history.

An aluminum soft drink can submerged in the Atlantic ocean salt water for years is surprisingly resistant to corrosion. The thicker square pull tab can last for decades. So road salt, weather these trucks will see I'm not really concerned about. The real area of concern would be aluminum/steel contact which obviously they have guarded against.

The worst corrosion and galvanic action is where dissimilar metals make contact with each other. The salt water in effect creates a battery and the electrolysis depletes portions of one metal and deposits them on the other. In the model you suggest of full submersion the one element left out is oxygen. Even a piece of wood will survive hundreds of years fully submerged with out oxygen, the element of life. Metals, when subjected to alternate wet/dry situations react while they are drying utilizing oxygen from the atmosphere (oxidation, rusting, corroding) and the sodium and chloride in the salt help facilitate the reaction when the electrons start switching sides and releasing energy in a hodgepodge of chemical reaction I forgot fifty years ago. ANYHOW the aluminum used in the bodies today has been alloyed and coated to resist the effects of salt water bath issues and we need only pay close attention to attachment points and hope the design and testing produced a durable and corrosion resistant vehicle.
They get plenty of oxygen over the years, have a look at the surf where waves break. Then feet of sand moves on and off the beach and with it the metal bits like aluminum pull tabs. Feet as in 8 feet of sand or more at times, its like a conveyer belt. Large waves will dig down deep and toss heavy metals like fishing sinkers and gold rings up onto the top of the beach so theirs this constant turning over and churning.

Aluminum corrosion
My 2017 F350 Lariat is at the ford dealers body shop having the box doors and rocker bottoms replaced because of aluminum corrosion. A ford rep came in today and said he’s never seen anything like this and asked the body shop if this qualifies for a ford buyback and they said absolutely. The dealer also said it was the first time they have ever had to say that. This was all caused by ford and not something I or the dealer did. I’m waiting for a call from the ford rep to discuss my options. I didn’t pay $75k for a truck that has now had some very extensive repair/rebuild done to it. Just posting to let people know about the issue

Aluminum corrosion
My son just posted the pic of my door. The. Body shop chipped the paint away from that spot and that was what was underneath. I have probably 6-8 more areas on both sides of my box and rocker panels and doors like that
