Montana Touch up Paint

Our 2016 Montana 3100RL has a small place on the rear cap (Legacy Edition) that I want to fix but I cant find a paint color to match. Even on the Montana owners forum I had no luck. This trailer has a full rear cap but the paint color is the same as the front dark grey that all of them had for a couple of years. Its close in color to my Honda but a little lighter so that was a no go. Anybody have an idea who would know the color or has found something that matches?
