We discovered water in the storage area. My husband removed the storage wall where the water seemed to be leaking and he found where a plumbing joint was leaking. It was an "elbow" type of joint. We purchased a replacement from Camping World...it did not look exactly the same, but the service person said that was the correct one. He installed it...checked to make sure it wasn't leaking and we thought all was well...until the next weekend when we went camping and water only trickled out of the shower head. Does anyone have any idea why this could have happened?
