wood or metal trusses
I know sales people will sometimes say whatever they think will sell the trailer- but are metal trusses really that much better than wood? What do you think?

When you combine aluminum with 2" thick extruded polystyrene and a composite material like Azdel (used in Lance Travel Trailers) you have what is basically a bullet proof RV. WoodGlue--/quote

The OP is talking about roofs not walls.
Extruded polystyrene is not a structural material it's an insulating material. Walk on a sheet of it between two saw horses and see what happens....
BTW, what material does Lance use over the roof trusses? You have to walk on something up there.
Keystone Cougar High Country trailers use 5 inch high arched STEEL trusses. The arched roof prevents water from pooling on the roof. Plus inside the arched ceiling gives you more headroom.
