New Northstar STC model

I have never owned a TC and am looking for my first. There is alot I like about this camper. The dinette and small dinette table was not as comfortable as I would have liked. I really liked the dry bath and with the rotating toilet there is plenty of room to get to the sink and shower. This was the cassette toilet. Tons of storage inside compared to any other no slide/single slide camper I have seen. One thing that did put me off though was all the exposed wood under the rear overhang. I wonder if that is going to be a longer term problem ??
