2008 Tiffin - Cummins 300 Is it a 6.7 or 5.9

I also have a 2008 Tiffin Fred (38QDB). Some of the marketing material from Tiffin incorrectly lists the 300hp, 5.9L Cummins as the power for the Fred in 2008. Unless yours was built on an older chassis, it probably has the 340hp, 6.7L Cummins. There is a very easy way to confirm the engine installed in the coach in question. Simply look at the color of the engine. If it is black, it is the 300hp, 5.9L engine. If it is red, it is the 340hp, 6.7L engine. I confirmed this in a discussion with Cummins when I kept getting conflicting information between the Tiffin marketing material and the seller's representation about the engine.
