What is this?

I was doing some maintenance today and never saw this before next to my hitch. Looks like an air line maybe for a brake system? If it is an air line I think I’m going to try and trace it back and disconnect it. I already have slow air leaks and want to eliminate potential problems.

Yeah, likely for an Air Force 1 toad braking system.

I have same connector for roadmaster toad air brake. Same on the toad.

Ok, thanks for verifying

It looks like one. If you follow that line back under the coach, you might find that line attached to a small accumulator tank to hold the air supply. If you’re pulling that out, you might want to get the tank out also.

First air leak I fixed on my coach was a fitting on that little tank!

Ah, the good old days when I was thin and agile enough to slither under the coach 😁!
