Canadian tailoring versus American scale in Allied truck logistics

Did the United States or Canada have the better truck logistics system during the liberation of Europe?

The American system was larger and sustained more activity. Canada's was probably slightly better pound for pound because it combined British experience with Canadian vehicle development and could be tailored to narrower commitments.

The American system had greater mass and supported a much broader military effort. Canada drew on British experience while developing vehicles of its own and working with American designs. The Canadian system is judged probably a little better pound for pound, partly because its smaller commitments allowed closer tailoring. That qualification matters when comparing a system optimized for a narrower task with one supporting a much larger and more dispersed force.
