“Started to leave for a trip with our 2010 Keystone Cougar 27ft 5th Wheel, got about a block away and the trailer overhang portion was started to come down on the back of our truck so drove back home and unhooked the trailer. Discovered that we have a flex frame issue, broken welds in the overhang portion. Total failure of the pin box while towing! Posed significant road hazard if we had continued driving. The whole overhang portion would have fallen on top of our truck and caused a wreck. Opened a case file with Keystone about the upper deck frame flex failure. …”
