When we bought our White Hawk, SWMBO hated the tiny mirror and the medicine cabinet. We asked the dealer if there was a larger alternative. They had us look at other trailers on their lot and see if there was a cabinet to our liking. Found one and the dealer ordered it and installed at our cost.
Worked out great!
