Farmerjon, I think the bigger 1/2 ton vehicles were referred to as "Heavy Duty" 1/2-tons. As I recall, all "Heavy Duty" 1/2-ton vehicles had five (maybe six) lug wheels. None had full floating axles, which were eight lug.
The primary issue (simplified version) was the fact a 1/2-ton axle bearing failure could possibly cause axle failure resulting in an axle braking and the wheel/axle stub would fall off. The full floating axles were and are a totally different design. The axles and bearings did not depend on each other. You could damage one with no effect on the other. You can break an axle on a full floating axle, and the wheel/bearings will still be intact allowing the vehicle to stay on all four (or 6) wheels. There are other considerations, but this was the most obvious to most of us.
