I like it a lot, Klaus! I particularly like the dirt and dust effect--it is quite realistic. How did you achieve it? And how did you get the antenna tiedown cable to remain straight and taut?
The only two minor things I would point out (and they are really personal preference) are that the antenna bends too sharply for my taste--the pictures I've seen usually show a more rounded curve--and the straps for the gear on the rear deck seem a bit too wide. That said, I'm willing to bet you can find real-life straps that are just as wide as the ones you have depicted.
In any case, congratulations on a very good build, especially since it was also an extensive conversion!
