The Cougar 366RDS features one of Keystone's most popular luxury floorplans with a raised rear den, opposing living room slides, residential kitchen, and spacious front bedroom. The elevated rear living room creates an open, residential feel that is perfect for entertaining or extended stays.

Don't wait — rear den Cougar fifth wheels are highly desirable and rarely stay on the market long!

50AMP power cable not included

Note: The JD Power link for the 2019 Cougar 366RDS did not resolve correctly during lookup, so a few specs were derived from the published floorplan and typical manufacturer specifications for that exact model year.
