I am not familiar with your coach but you say the living room slide coming in causes a water leak. I would have thought your kitchen slide moving might have been a more likely scenario. Probably the slide movement is also moving a pex water line and fitting somewhere under or inside the offending slide area. Likely a cracked or loose pex fitting or line now. Is the leak occurring on the ground under the offending slide or inside the coach? Of course the easy fix for travel is shut off the water pump. Try to see where the water is coming from specifically so you can determine a best course of repair.
