Bigboomer, we have the copper patina interior on our 2014 model 3725. It is kind of unique, in that like you, it's the only one we've seen in that model. Every other one that we've looked at has mocha, or something else. It appears to be "one of a kind" for us, too. What we did was delete the leather furniture upon purchase, because we already had a full set of La Z Boy recliners and "entertainment center" viewing console setup. We don't like leather, and had the other furniture from our 3400 we traded in, so we just swapped. If you like, I'll PM you with pictures of our setup.
