I finally found the low point drains on the 5th wheel I've had since July 2008.
Went looking for them because it's going down to 25 F tonight and the next few nights here in mid-Georgia. Looked for them before but never saw them. I was looking down the street side. They're under the bathroom on the curb side.
Didn't do a full winterize because we want to go out a time or too before Christmas, but did drain everything, button up good and set up an electric heater.
And these are plugs or caps. I think I'll put two little valves there just to make it easier on my self.
Soon as it warms up!
