Salem Cruise Lite build materials

Hello, I am new to the Forum and new to Forest River, though we have had camping and travel trailers for 35 years or so. After an exhaustive search online for particulars on what materials are used in the building of Cruise Lite Western version trailers, I have found nothing. Does anyone know where I could get this information? I also wrote to the factory, with no answer. I want to know what the floor and ceiling are made from, hopefully plywood and not pressed wood. How thick is the material? And what is the wall framed from, material and size? I know that the Cruise Lite is considered a mid-level entry trailer so it won't be built like a Northwood trailer, but we all should know what materials have gone into the making of our sizeable investment.

I hope someone has the answers for me. Thanks in advance.
