Welcome to the forum. You didn't indicate what year of Cougar this is but I did look at the Cougar inventory for 2011 (Trailers and 5ths) and cannot find any Cougar with that designation on the Keystone website (
www.keystonerv.com). I am only guessing, but it might stand for
West
Coast
Version --- WCV). Keystone does have two categories --- West and East Coast versions.
If you were to provide us with the year and model, it would help members with their responses. Thank you.
