Let's do a quick example using a typical rear axle, with dual wheels. The GAWR of the axle is 14,500 lbs. The tires will be selected so that their weight rating will support that axle rating, and not much more. That means that each end of the axle can support 7,250 lbs.
Now suppose the coach is loaded so that the rear axle is at it's limit, and the tires' limit equals the axle limit. If you weigh the axle as a unit it will show 14,500 lbs and you think you are good. But if you weigh each end separately you might find that one end weighs 6,250 lbs and the other side weighs 8,250 lbs. The axle (and tires) are still at their limit, but the heavy side is 1,000 lbs over the limit.
Now, you'll say that it's impossible to have such a difference between sides - it's not that hard to see several hundred pounds difference. Think of where your refrigerator is, where your generator is, propane tank, batteries, holding tanks, hot water tank, bedroom closets, outside storage bins, etc. It's actually almost impossible to find a coach that has an equal 50/50 weight distribution side-to-side on the axles.
