That vehicle came up in the Wish List for 2024 discussion. If it ever hauled something like a T30 or M103, that would make a fun combo to model.
The same guy who led the T26 project worked on the Twister. That was one of the coolest vehicles ever built.
Still do not understand what the US Army had against doors on support vehicles. 
At least the T26 had a roof.
Would be fun to own a Hunnicutt style book covering US tank transporters. Maybe I already own one. My library far exceeds my memory capacity. 
My favorite quote from the video was, “a design that never saw the light of day”. He says that while showing the prototype running around doing stuff.
