Previous year's trailer specs & many floorplans are also available on the Keystone website, if that model is still in production.
Example: If interested in a 2008 Cougar --- Go to the Keystone website, and then the current Cougar line. Click on the SPECS tab,
and scroll to the bottom of that page. Each previous production year will be listed there. The Cougar info is available from 1999 to present.
Once you've opened the 'year' page, click on the model (white box, at bottom) to enlarge/show specs; some, but not all, also include floorplan & photos.
Some past brochures are also archived online, although most only a few years... and again, only if that model is still in production.
