On or about April 27, 2021 the driver's side rear taillight assembly randomly fell off between Phoenix and Tucson, Arizona on Interstate 10. The assembly is large, containing the taillight, brake light, turn signal light and back-up light. It could have (and may have) hit another vehicle or at least caused it/them to engage in a dangerous turning maneuver to avoid hitting the large assembly while on the freeway. In addition, the RV was then rendered unsafe and in violation of the laws of virtually every state, as well as federal regulations, due to lacking the required lighting assembly. This has also happened to another RV unit from the same manufacturer (Regency). The driver's side taillight assembly fell off this RV during windy conditions on Interstate 40 while traveling through Arkansas on April 2, 2021. There are photos of the missing assembly for both RV's. My RV was inspected by a collision repair facility in California and their determination was two fold: 1) the RV body was molded in way that would not permit the taillight assembly to properly fit in the cavity. The tolerance was off by up to 1/4 of an inch. 2) the taillight is a stock mercedes sprinter taillight assembly which has three hard point connections (top middle, and bottom. However, the body of the RV only has two points to connect the taillight assembly (top and bottom) thereby leaving the middle area open to intrusion by wind and other elements. As a result it was very difficult to find a facility to repair/replace the assembly ( they "did not want to touch it"). It has now been replaced by a collision facility which used a silicone sealant and HD velcro in the HOPE that the assembly will not fall off again in predictable weather conditions. There was no warning or other indication that the taillight assembly was going to fall off. Finally, Regency claims to manufacture just 200 to 250 of these units annually. This incident therefore involves 1% of their annual production.
