[Mogolfers]

When touring the factory a couple of weeks ago our tour guide pointed out that Doubletree replaces the outside plastic housing on zerk fitting on the Mor-ryde and Equa-flex with brass to keep it from wearing. Then he pointed out that the Zerk fitting should be greased twice a year. It was news to us! Looked through manuals didn't see anything in regard to greasing fittings. Good thing though, when under the trailer I discovered our black tank had one side with two screws not in to anything.
