Time for the base for the rear seats. Yup that’s a self contained toilet in between them. It has a built in 12v fan and external vent so should it be used, the stank should stay down. Thanks to CA emissions requirements in order to run a pre 2012 diesel engine, you have to be an RV meeting 4 of the 6 RV requirements. This puppy will have all 6 just incase the inspector decides to be a PITA! The rear seats are out of a 2019/2020 GT350R however they are going to be recovered to match the front seats which are out of a 2020-2022 GT500.
