Hi Dale,
Call Lance @ 661 949 3322. I think its extension 510 over there. They can give you the actual truth about the model you are looking at. They're actually VERY helpful. My understanding was alum framing started in 2008 but I could be wrong and wont be the first or last time, today...!
I definitely would do that before buying any used camper. They can send you schematics and everything but should easily be able to answer if it has some or all aluminum framing.
My memory says "some" alum starting in 2008, meaning that some parts of the camper were NOT using alum yet.... but - please correct me if you find out.
Be careful and good luck...!
