I’m guessing your not happy with Ford and GM’s all new aluminum beds then?

GM doesn't have an aluminum bed, still steel. What GM and Chevy have that's aluminum is anything with a hinge. So, doors, hook and tailgate. The bed itself is still steel.

Interesting. Just looking at the diagram of the 2019 Silverado that’s a lot of mixing of dissimilar metals. In the ford it’s a pretty clear demarcation point that’s easy to electrically isolate.

It will be curious to see how all the brands stack up corrosion wise in the next few years.

I guess GM couldn’t stomach using an aluminum bed after the 2016 ad campaign against ford.

Aluminum is good for resisting corrosion, but it is usually less rugged than steel. For a truck bed there are really tough plastic liners. Can also get a Lear or some such cover for the bed.

For a steel bed, get something to protect against corrosion, and for an aluminum bed get something to protect the aluminum if it is too soft.
