The Copper Canyon was part of the 'Sprinter' line until this last year, and unfortunately the 2005 brochure isn't archived on the Keystone website.
There was a Dometic refrig service bulletin (recall), which may have included this model but chances are it was already repaired.
Check for other recalls on the website:

Hope this helps... and welcome to the forum.
