Ones I know of in 2013:
Lance
Coachmen Apex & FreedomExpress
Heartland North Trail
Skyline Koala
Possibly Gulfstream GulfBreeze?
Evergreen Everlite uses compositek but it may be an option in 2013. Standard before that.
Think all these use wood in the roof. Evergreen Everlite started that in 2013.
And all use wood in the floor except Evergreen Everlite.
There are also the Aluminum and Al-laminate trailers with no wood shell.
