Truck design....

While I was stopped for gas/food on a motorcycle ride somewhere, I saw a rig that looked like it had an extended chassis, because it appeared that the owner had installed the works for an enclosed toy hauler between the rear of the cab and the forwardmost point of the trailer. It looked to me like the owner had it in such a way as to allow a powered (by the running engine) platform that slid outward and lowered/raised with tie downs for a 1000lb motorcycle. I wasn't paying much attention at the time, but does this exist in a production situation, or would it be custom fabricated?

 

I seem to remember the guy had a GL 1500 inside, this is a complete touring motorcycle with saddlebags and a dry weight of about 800 lbs.

 

Is there a video of this being loaded?

 

I wanted to get a clear picture of how the bike is secured; from the distance between the camera and the bike; it was hard to tell how that is accomplished, plus the video only shows the platform in action. I was hoping to see the loading process from empty to secured inside.
