Actually, the article points out that a good portion of motor homes use the "suped-up" Turbo 400.... I think they called it a Turbo 475 A standard Turbo 400 used heli-cut planetary gears while the Turbo 475 used straight cut planetary gears.
The $1k I mentioned above is for brand new parts... they did say you could get a motor home version and swap the gears over.
Unfortunately, they said there was no physical way to tell a 400 vs a 475 externally
makes me wonder if the military cuccv 1 1/4 tons used the 475 behind thier diesels?
