Actually it is a Safety Relief Valve.
When tank is made/used for RVs the relief valve is installed at bottom with a tube that goes to top of tank area (Vapor).
If relief valve was installed on top o\of tank like a skid mounted/residential tank then should relief valve open it would exhaust vapor inside an RV. Not a good idea.

That is an RV tank. And view is from side.
