I have a 2001 28 ' Cherokee 5th wheel by Forest River. I bought is used in 2006. The living room slide leaks. It drips out from the back corner right onto the cusion and me when I sit there. I have covered it with 2 mil thick plastic drop cloth and it still leaks. I covered it with a large tarp that completely covers the slide as well as half the roof and it still leaks. What do I do? My A/C also leaks. when I run it constantly, especially in the summer in FL. I have noticed that the back wall behind the cabinet is wet and deterioating. I have looked all over the ac unit and can't find a leek. What can I do?
