I have a 2019 innsbruk 266BH, I believe that is the model number. It has the exterior door to the bathroom, the bunks are on the driver side.
All the bathroom plumbing, shower, toilet and sink are to the black tank. The gray tank is only for the kitchen sink. I found this out the hard way when the shower started backing up and the gray tank was empty, but black tank is full. We just keep the black tank hooked to the septic hook up and keep additional deodorizer. It seems to keep the black tank clean by having the shower water and such fill it up.
