Brand new travel trailer delivered from the factory with damaged brake electrical connector to the ABS Module. This resulted in an immediate and total loss of trailer braking capability while towing the vehicle, creating an extreme safety hazard and increased stopping distances on public roads. I was able to reach my destination with extreme caution and upon investigation I found the clip that’s supposed to keep the connector securely in place, completely severed and the entire harness loose and disconnected.

What 2026 Keystone Cougar owners say
Most recent owner complaints, unedited.
Camping world Hamburg delivered to me fifth wheel they Ammit they did not have inspected causing Catastrophic structural frame failure and pin-box cross-member buckling (Frame Flex) engineered within the upper deck chassis frame. This structural failure has caused widespread, secondary body panel collapse, including deep spiderweb fractures tearing through the upper fiberglass radius wall paneling, vertical trim moldings violently warping and splitting open, and the upper passenger-side roof cap seam ripping completely open. The failed components have been placed under an immediate "no-tow" safety mandate to preserve evidence and are fully available for a driveway physical evaluation or engineering laser-scan upon request at my residence.
