I admit I haven't read every existing post on this fertile subject but will share my question anyhow.    I can hear a leak - it's at the rear slide seal where it splits under the slide - clearly audible from the outside.    Can anyone tell me what I need to take apart to get to these components?

Thanks in advance,


Chuck,

I heard the same air leak noise when i walked past my rear left slide last week. To get to it there is a panel under the bed held down by screws and the 12 volt lift for the bed base. Removed the panel and their was the 12v valve, regulator & turn off valve that goes to the air seal and the air leak noise. When i put air leak finder on this assy. very little air was coming out around the valve stem. Thought i would just replace the valve......"wrong".
Turned the valve off and the noise stopped. Now i believe their is a big leak in the air seal that go"s around the slide out. LOOKING FOR SOME PLACE TO REPLACE THE SEAL.
