Too many people coming up with silly ideas and drinking way too much koolaide. The chances of an engineer or someone who builds a unit getting into a defective unit is most likely less then 2.5%. 90% of the issues people talk about in my humble opinion come form the unit being hauled 4000 miles at 85 mph buy someone who does not care. It arrives at a dealer who is paid good $$$ to check it out who does not do it and it gets sold to you.
Everyone here has a chance to pay 15K more for a base unit or 100K more for your higher end units compared to mass manufactured units and get the quality you want and choose not too. Stop complaining about it!
At the end of the day 95% of us would not have the RV unit we have if we needed to spend the extra money, be happy and go camping.
