Bob (and everyone else out there with knowledge),
Maybe this question should be a separate post since it doesn't really deal with the original issue of the post, but who does the initial installation of the entertainment systems?
Not knowing how the whole RV industry works, my first assumption would be that the RV manufacturer installs them as they are building the unit. Then the unit is shipped to the dealer where it is finally sold. But then I started thinking...again not knowing how the auto industry works either, I do know that some equipment is boxed and shipped to the dealer when a new car/truck is ordered, for installation by the dealer or a third party. Is that the way it is in the RV industry?
The only reason that I ask is that it seems that there is a wide variation of how systems are installed in identical units around the country. If the units are being installed at the RV plant, then there are some serious quality control issues that the manufacturer needs to address within their company. If they are being delivered to dealers for installation, there there are still quality control issues that need to be addressed, but it makes it that much more difficult for the manufacturer to control.
You would think that a RV company would do a better job of controlling quality. Even under warranty, when a unit is returned to have a 'defective' stereo removed and a replacement ordered and installed...the dealers aren't doing that for free! I would have to imagine they are charging that work back to either, in this case, Forest River and/or Concertone. (And this issue isn't relegated to just the entertainment system, but since this is the issue being discussed, that is where it will remain).
Anyway, in this and other posts there have been reference to crossed wiring, loose connections and so forth, so you can see the vast difference in installation and quality.
