Well, in my rig it's black iron. The store clerk in Canadian Home Depot was also 100% positive that galvanized is not to be used in natural gas lines (they don't know anything about propane).
I am not sure whether black iron is better or worse than galvanized. After my trailer survived a little flood in Mexico and wet mud came up to the level of plastic sheets covering the belly - the black iron Tee corroded on one side, where it was closer to flood waters. I've sanded the rust out and painted it with Rustoleum. So, from my point of view, black iron does need some protection on the outside, and galvanized coating provides such a protection.
