2008 Jayco Seneca HD
As a 2008 with a 330 hp 6.6L Duramax, this will have a DPF, but no DEF right?

No DEF in 2008. The standard engine in all 2008 Jayco Seneca models was a Duramax 6.6 diesel rated at 330hp according to the 2008 Jayco sales brochure which can be found at the Jayco website. I have a 2008 Seneca 34ss with the 330 hp engine. I believe all earlier years came with the 300hp engine.
