Maybe this doesn't apply to your coach:
"According to the NFPA 1192 Standards on Recreational Vehicles, “each vent pipe shall pass through the roof and terminate vertically, undiminished in size, not less than 2-inches above the roof.”
It does say "each" vent pipe which may be just one but does address what the requirement is for a pipe designated as a vent.
