We just spent close to $3,000 getting new seals for the slides and the roof resealed, plus other things. The cost isn't the problem. We have a leak in the back wall of our 2009 Big Country 3500RL. Can't believe something made in 2009 would fall apart this fast! Only one side of the wall by the back window. The wallpaper inside the upper cabinets has NOT bubbled .....the problem is only right where the top of the window starts...down to the floor. I figured it wasn't coming from the roof sealing that we JUST paid for . We are in a campground in San Antonio with a blue tarp over the back window area. I'm sure we look like "trailer trash" The wall is mush and I can poke my fingers though it. Don't have clue how to find the leak without ripping the whole wall apart. I can't take the trailer into a shop right now because we are living in the RV until our new house closes...about 18 more day. Praying that San Antonio doesn't get anymore rain for 18 days. Just bought a new 60K truck to pull this RV with, now I'm wondering if it's all worth it.
