Our Forest River Georgetown 5 Series 36KB motorhome has experienced TWO separate failures involving the rear hitch/tow attachment system. The first failure occurred while towing our 2021 Jeep Cherokee Trailhawk. The hitch assembly/connection failed, the jeep almost became detached on 95. We pulled over and jeep crashed into RV. The motorhome and Jeep was repaired through our insurance/Good Sam assistance. We have now experienced a second failure involving the same general hitch/chassis attachment area. A weld/attachment connecting the hitch structure to the chassis failed and came apart. This failure has raised serious concerns about the structural integrity of the hitch attachment and the safety of continuing to tow with this motorhome. These are two separate failures involving the same critical towing system. Failure of the hitch or its chassis attachment while traveling could result in separation of the towed vehicle, loss of control, property damage, serious injury, or death to occupants or other motorists. We have photographs and repair documentation from both incidents. We have also identified publicly available information from an RV repair facility discussing failures involving the same or substantially similar hitch/chassis attachment area and describing such failures as recurring/common. We are preserving that information as supporting evidence. I am requesting that NHTSA investigate whether there is a broader safety defect involving the hitch/chassis attachmen
