Just shows ta go ya, makes no difference the make, model or system, the RV industry must have the biggest screw ups ever being paid for an attempted day's work.
Given how the automotive/rv (mass production) industry works, these individual components are engineered by a 3rd party. {insert RV manfactuer name} takes these "systems" and integrates them into a complete unit. I have similar problems in construction industry. Exacerbated if I come into it mid project to clean it up. I have certain vendors that are automatic first choice because if something goes wrong they back it up. Others that get their crap ripped out, no second thought. Is Dutchmen flawless, no; compare to the "overall" quality of construction / systems it was by far the best. I looked at Jayco, Grand Design, few others. To go the next step would have been 2-3x as much if not custom build. My two cents, based on 30+ years in construction industry.
