Moved thread from the General Community Discussion section to the Motorhome section's Berkshire sub-forum for better help from other Berkshire owners and possible factory support.
You may have some luck by contacting the Berkshire Parts Dept; their number is 574-522-1747 just have the last 7 of your VIN and ask for Jackie and she will be able to see what shades are in the coach and what parts may be available.
