I have a 2012 Mountaineer 347tht and it has wood cabinets and a corian countertop
When I was researching prior to my purchase of my rig I found this brochure from the model year.
It was my understanding the Montana High Country was more of a lightweight package, also available the same year model. (See manual link).
