Does anyone know if the factory hitch used on the 2015 Outback is compatible with the 2018 (or even 2017)? My vehicle was just totaled due to flooding. I was told I could take the factory hitch off the vehicle by the insurance company (just not the wiring harness due to saltwater intrusion). I hate to see it go to waste as it is in excellent condition and costs a bit of money for the factory hitch. Thanks...
