CF-18/19 Docking Station or Backpack

I've been curious about the options for docking stations or something to mount the toughbook to. It's called the backpack and docking station for the Toyota Techstream. The backpack is the unit the Toughbook mounts to, and that backpack can then click into the docking station to charge. I have two of these backpacks, but they're usually very expensive to get if you can even find them. With the number of experts in this community, I was wondering if any of you in all of your modding and toughbooking have ever come across anything at least similar to this. I've browsed accessories and docking stations until I'm blue in the face, and I've only been able to find some pretty plain docking stations and hand straps. I've included a couple of pictures of one of mine with the backpack to show you what kind of thing I'm looking for.
I would even be interested in knowing about similar things for other models too as I might be considering getting something else.

 

If you are looking for a vehicle mount there may be less expensive options. You can usually find used mounts on eBay for $50-$75 or so... But you would need to fab up the mount from the floor to the mount, a fairly easy process if you can weld or drill and bolt.

There are a few cheap ones like this on ebay now...
