Truck shop in northern Germany?

[Friis]

I know this may be a long shot, as the main part of you guys are living in America, but the thing is that I am looking for a good truck shop that will work on my F-250 in the northern part of Germany. I live in Denmark, and it is considerably cheaper for us to get our cars fixed in Germany, especially US trucks, as the F-250 is a rare and special kind of vehicle over here (almost no authorised dealers/shops).

Thanks.
