   Very helpful, thanks.  Regarding the smell, I'm not convinced it   
   was a burned wire (or component).  Something hot, but maybe not   
   burned.  Given the past history with the dealer (many, many months   
   to get a slide out repair), I'm not sure I want to take it to   
   them.  It's still under warranty though, so it seems they would   
   be the best option.
