just replaced my old EZ loader with a new King, really like it. I am not sold on the oil bath hubs on boat trailers that get dunked in water, especially if the they are still warm. I have seen bearings with grease burn up, but that is usually due to neglect of maintance. I have also seen truck trailer bearings with oil bath hubs burn up, one little crack in the cover and all the oil is gone. The guys at boat country told me my lights are waranteed for life (I hate boat lights and working on them, so this was a plus for me).
