Hi Eddie1,
If you follow this link
AW119 Ke | AgustaWestland
Click the brochures tab. Open the PDF file and on the 3rd page you'll see some interior images of the 119, including one image showing the single stretcher configuration, which in my opinion is a more viable option.
Two stretchers in the cabin looks to be very cramped. A slightly overambitious move by Agusta. The single stretcher image shows some medical equipment on board also.
