Just a couple more notes. The voyager rack, (and im sure with the urban too) you can have it made to your specs. So, for example, the rear bar that Finlayforprez has but I dont. Or the 'floor' on the front part that I have, etc.
So do lots of searching of images, because you really can customize. I bought mine from Kaaae, but it was exactly what I wanted. Mine has mount points for lights on the front, one for the rear. you can have them add shovel mounts, hilift, whatever you want.
The voyager full rack (normal) also has the little bump in it like the urban rack. I wanted the low profile in part because its flat from front to back. I like to flatten the top and hide the roof bump a little.
You also dont need any factory rails for the voyager rack.
Details are fun!
