One observation I can make here is high end or low end you get the same cheap plastic exterior oven fan exhaust ducts, roof vent pipe covers, outdoor shower access doors etc,. Airstream is the exception to these. I have replaced my shore power access port door three times. Overall the RV industry should be ashamed of the lack of pride in the product. People spend their hard earned money and get junk. Just my opinion based on experience, talking with people and customer complaints I read about right here
