We bought this 2016 Cougar brand new.  We used it on four trips for total of less than 5,000 miles.  I owned a horse and cargo trailer business for 13 years and I know what is quality constrution on trailers and what is poor construction.  I chose the Cougar brand because the construction quality is excellent.  It's framing is 6" steel tubing and the slide out moves in/out with a heavy duty screw system not cables (cables stretch and eventually break).  This trailer has had absolutly no problems with it, everything works perfect, no leaks and it is in brand new condition.  The tires still have the rubber nubs on them.  This RV Cougar trailer is LOADED!  It has a highly desirable layout and is very roomy.  Even the bathroom has lots of room.  The RV also comes with some added accessories and includes a weight distribution hitch set up for your truck.  It tows effortlessly.  This is a RV trailer that has lots of room, easy to tow and maintain.  There is lots of storage space.  It also has a Winter Package!!!
This trailer looks and feels brand new.  It is extremely sharp looks.  Tows perfect, has a large amount of storage space and the layout is has been well thought out and is very roomy.  The size and the layout, plus the fact that it is a Cougar, makes this trailer highly desireable.
