Rounding up 5 or 10 psi should cover any error by using the total axle weight average rather than weighing each end separately:

In the load and inflation tables, SINGLE means an axle with one tire mounted on each end, while DUAL means an axle with two tires mounted on each end. The loads indicated represent the total weight of an axle end in an RV application. When one axle end weighs more than the other, use the heaviest of the two end weights to determine the unique tire pressure for all tires on the axle. The maximum cold air pressure for each axle may vary, depending on their weights. These tables are applicable for all RV axles, whether or not they are power-driven.

Gordon is completely right, the Michelin tables reflect the whole axle weight (load) and you do not have to divide. The Michelin tables do it for you, no dividing. You have your axle load already, look up the corresponding air pressure and follow the advice about rounding up. Sorry I misled you. Thanks Gordon.
