I have just finished staining a door that we are adding to our trailer. I used varathaine brand "Early American" that came in a black tube (like a large tube of toothpaste). I had taken one of my cabinet doors to the store to match the colour. It is the closest match I could find.
Our trailer is a 2011 model, but Jayco has kept the same cabinet colors in 2012. I am camping right now, but will post a photo of the product when I get home tommorow.
This colour would be worth taking a look at for a match. You can just rub some inside one of your cabinet doors where it doesn't show in order to check it.
