black hose next to tank drain question

[rickjp]

What is the the black hose that looks like its got an air fitting on end? It is right next to fresh water tank drain. Thanks

Just guessing: ... could be a propane line. The fitting sounds like a "quick connect". Where does the line go if you follow it back?

[rickjp]

It runs to other side away from propane. It has a female connection. Could it be for slides?

A picture would help.

Might be for air blow out? Yep, a picture would help :-)

Dollar to a donut it is a propane outlet.

I have the same rig and I can tell you it is the propane low pressure quick connect.

Thanks, just wanted to make sure it didn't have anything to do with water as it is getting cold here!
