I had made my own, but now i just keep my hitch on all the time for "cushing"
Anyway, what i did was buy those 2 dollar plastic oval ones from an auto store, order from Grady your boats oval emblem, apply it on the 2 dollar hitch cover and you have a million dollar looking hitch cover. Oh, mine got stolen off my truck when i had the Bimini 306, so if you see one around, is mine.
