On a Boondock 320S, it is on the drivers side under the seat screwed to the rear-most bulkhead approximately between where the Nautilus and External Shower are on the outside.

It makes sense to move the pump to be close to the water inlet, and it’s incentive to NOT leave the water pump on at night....at least an incentive for the one who sleeps on the driver’s side of the bed😂. I could just see a dog waking up to the sound of the water pump and almost jumping through the ceiling😳Verna, Columbus, IN

Well, they are really standardizing everything. The 2021 model no longer has any of the plumbing valves or water pump under the sink as seen in this picture from Mandy’s CS video. It must be under the driver’s bench as well. Lots of free and clear storage under the sink now!
