Freedom Express 279RLDS

Hello,

I am trying to winterize the trailer. This is my 4th trailer so I know the process as far as how and what I am going to do but it's the first time going through this one. I can't seem to find the low point drains. Does anyone with a 279RLDS know where they are? I don't want to start cutting into the underbelly playing hit and miss to find them.

Thanks,
Mike
