Don't forget how much stuff you can put in a trailer, it adds up quickly. Watch The Long Long Trailer for an entertaining example.

On half ton axles the axle shaft provides power to the wheel and it supports the weight of the truck too. This the reason you see old Ford trucks alongside the road with a rear wheel broken off. A 9 inch ford weakness. A 12 bolt axle's bearing will fail but generally the wheel won't leave the truck due to the C-clip.
On 3/4 ton and larger axles the weight of the truck is supported independently of the axle shaft. Thus the axle shaft only has to deal with stress from the axle twisting. The 3/4 ton bearings have at least twice as surface area to carry the weight.
