Sorry to hear this. My 2021 Imagine 2500RL will "leak" underneath if I overfill the freshwater tank, until it gets to the proper level (it's the overflow). The interior leak is more of an immediate concern to me, and would want to know where exactly that is coming from. Hope you can hunt that down. I assume the bed is near the plumbing intakes, pump and valves? Good place to start looking, I would guess.
