dorgene Report post Posted March 14, 2016 Kent, The 2007 Country Coach you are looking at - does it have a 2006 engine? If so, it will not have a DPF (Diesel Particulate Filter). 2007 engines required a DPF. Note: This applies to the model year of the engine, not the model year of the chassis or coach body. In my view, an engine without a DPF is more desireable. Share this post Link to post Share on other sites
