Wheelbase to length ratio. What does it mean?
When you divide the wheelbase by the length of the motor home, you should have a wheelbase-to-length ratio of 53%. This ratio gives us a good idea of the handling characteristics you can expect from t...

Another way of viewing poor WB/OL coaches is to picture the wind vane on top of the barn.
Most of the surface is behind the fulcrum. So, the slightest wind makes it point toward the wind. Lots of rear overhang acts the same way in a cross wind. Again, not a Class A, C, diesel or gas issue.
Can engineering overcome this-- sure. A good example is the Foretravel 34'. Poor WB/OL ratio, BUT (yes, big but) it has 8 outboard air bags and 8 outboard shocks that help defy physics.
