I tend to agree with Oman...I don't think they will sell one just to sell one. I've got one of their vehicles (and yes, it does have the windshield decal), and I asked for a decal to go on the side of the vehicle where the Jeep logo is at behind the front wheel. They wouldn't do it....they said they reserve that decal for vehicles that have custom paint jobs. Factory paint jobs only got the window decal, wheel decals, and decals on the rocker guards. They did however embroider their logo into the factory seat covers while they were torn apart for the seat heaters....although you can't see it due to the wet okole's covering them up....which also have the AEV logo screen printed on it.
When I spoke to them in person out in Moab, they definitely put across the impression that they don't like having their name on anything they didn't put together themselves. They didn't come across like jerks about it...just matter of fact.
