I sent these guys the attached picture and they mand me three for under $50.00. I'll attach a picture with one installed.
trailer decals, rv decals, race trailer decals
Just send them a good picture and tell them what size it should be and they will make it. They can also do thee Compass Rose if you can get a decent picture of the one on the back.
Better yet, call them and they will walk you through the process.
