I just noticed in those photos the gal trailer looks rusty. It's only 12 months old and it's not rust, it's leaf tannin stain from when I parked it under a tree for a while without a cover.

Many tannins are a good preservative. We've got thousands of Qld Box trees for street trees in Perth, there's one right outside my house. Anytime I park my Hilux traytop under it, the floor stains purple blue from the Box tree tannins - but it never rusts. Jacaranda tree tannins are quite corrosive, and the leaves built up everywhere.
