The passenger side landing jack on our Keystone Cougar fifth wheel suffered a major failure last week. I was in the process of jacking the trailer off the truck when I heard and felt a loud clunk.
In fact, my wife who was inside setting things up, immediately looked out the window and asked, “What the heck was that?” “Not sure” I replied, but I knew something was not right with the jacks.
I decided to retract them again and that’s when I saw the passenger side landing leg was not lifting up.
