Hey Jim, that's a little confusing. The engineers said it's not good to have a wood roof with a metal frame, but you said the Solitude has a metal frame and wooden trusses for the roof? Can you clarify that?
After reading my post, even I was confused! :S
Regarding the roof. It is plywood secured to wood trusses (16 inch on center). The walls and floor have a metal frame. The metal studs in the wall are bonded as part of the wall manufacturing process with the interior panels, insulation and exterior fiberglass.
Reading back through the thread, another primary reason for using wooden trusses it that when the wood roofing material is screwed down, the screw bites all the way into the wood vs a very small bite through a hollow metal structure.
I'm summarizing a very long thread, so I'm putting a link here if anybody is interested.
