I will post some images in a subsequent comment.
I have only seen photos of the hide-n-side. I have no idea how many were built before the legal wrangling with Chrysler began. There have been other similar designs as well, such as the Stahl Grand Challenger and the Royal Sport Body.
Unfortunately as best as I can determine in 2016 Scott Clare, Neil Long, and their company Innovative Truck Storage, Inc lost their appeal in the case of Scott Clare v. Chrysler Group, LLC, Case No.. 13-11225 (E.D. Mich. June 4, 2014) which resulted in holding the lower courts ruling that Clare, Neil and Innovative Truck Storage had infringed upon Chrysler's patent. So I suspect the Hide-N-Side is not ever going to be built. The Royal Sport Body (never made for Dodge) went out of production due to errors made during manufacture by one of their vendors which resulted in a bunch of unhappy customers and costly warrantee claims on the finished beds.
So I make my own. It is a bit different from all of them too.
