Hello and welcome. If you go to the Keystone website (
www.keystonerv.com), click on "Cusomer Service" and follow the links, you will find the Owner's Manual for various years there. Keystone does not publish a new manual every year nor does it publish one for each model. You will not find a manual that pertains specifically to a 2004 Cougar. Find the year closest to yours and that will be the best you can do.
