Well, all of that stuff was on the Interweb in one place or another. The trick is knowing that Colani (or any other specific designer for that matter) penned a ground effects vehicle, roadster, GT, exo-atmospheric lifting body etc.
If you look at the way the motorhome is articulated the engine and front wheels pull the thing along and the cockpit and living quarters are on the 5th wheel element! Are you sure you would rather have a Winnie instead?
Bottom line, Colanis stuff is mad

as a box of frogs, which is why you don't see it around very often
...Although, spookily, I understand that Colani was consulted on the design of the dashboard for the first generation Ford Ka, so you might have been exposed to more Colani than you thought
