Dan,
I'm not sure if this helps or even answers your question..
The brakes on the GN are less than ideal!
They fade away quickly at higher speeds and it would seem they would act the same way with a heavier/loaded truck.
I don't know if this is due to the master cylinder or the GNs having stock Regal brakes.
