Also worth noting is that Recat is posting up free 3D models on Thingiverse for door handles, badges, grills and more are being added every day.
I wouldn't be surprised if Recat themselves had a new skid soon, thought maybe they'll stick to the cosmetic stuff.

I really like that they've done this.
Oh and on the hump I'm not a fan of it but it wont deter me from this rig. I have seen these kind of humps act as a pivot point when high centered on it, the truck might do a full 180 before freeing itself as it is will just pivot around the hump. but not a deal breaker.
