The semi-float 14-bolt was not just a light-duty option. It was installed even in the heavier "c6p" 8600-gvwr 3/4-ton trucks. Evidently, GM considered it heavy enough for large payloads.
GM did install the full-float 14-bolt in the big-block c20 trucks. My theory is they assumed that combo was being purchased to tow trailers with. The larger ring gear on the full-float axle would hold up better to towing.
