I had Karl make 2 of these up completely custom for my G, for my recent Utah trip. Before I could mount them on the truck I had already bought a bigger vehicle and didn't need the plates afterall.
All aluminum, laser cut(I believe), professional black powdercoat. Very useful to mount trail tools, Rotopax, waterproof duffels(I got 4 110L Ortlieb duffels which I was going to use as "saddlebags"), etc.

Here's what the standard ones look like;

Here are what my 2 custom units look like (no Mercedes star, 2 more large holes, 8 more slots for tie-downs)--sorry for the blurry pics, didn't know the lens was a bit smudged;




Brand new, never used, packaging just opened up to look at them and take pics. They're packed back up in their original packaging.

Priced less than the standard plate, no custom fee, no longer wait time for a custom cut;
$390/ea + S&H to you

*1 of the 2 has already been sold, so I only have 1 left*
