I was looking through the paperwork for our new-to-us 2008 Beaver Contessa and found conflicting information. There is a data sheet that shows most of the equipment installed at the factory, along with model numbers, etc. The Monaco data sheet states a C9 400 horsepower CAT engine. However, we also have the window sticker sheet that shows the standard engine as a C9 400 hp but the options list a C9 425hp upgrade for about $8900. So which is right, the Monaco data sheet (it shows our VIN) or the window sticker sheet?
Is there a way to tell by s/n?
