I just discovered these at my local Hobby Lobby too. But the wheelbase on the CCKW 353 scales to 1/144. The prototype truck is small by today's standards, and does still look good for N scale. I plan on shortening the wheelbase on the trucks to use with the micro trains artillery flat car loads. Often the artillery haulers had the shorter wheelbase.
The wheels/tires can be used for other trucks and construction equipment, too.
