We just completed a 7500 mile trip across the country that went perfect, no problems with our 2009 2900MK Sundance. We arrived home and started to clean the 5er when we noticed the living room slide was leaking.The water seams to be coming from the rear inside bottom corner. We noticed the carpet is pretty wet and the molding is wicking water up about 5 in. The walls are dry. Any suggestions where to look for the problem as I'm fairly new to trailer world. Thanks
