Wheel base to over all length ratio is more forum/internet nonsense.
MY 95 Bounder has a ratio of .479 and it drives great! 190" wheel base, 33' long. Best thing is the turning. Then there is the diesel owners talking about rear over hang on the gassers. My gasser has a 13' over hang. Diesel pushers have a 12'+ over hang, depending on chassis. More forum/internet chatter. Bah Humbug!
You'll see folks telling how horrible or how great their rig drives, no matter the ratio or total length. No one can document the ratio thing.
If set up correctly, they all drive well.

It's called physics.

OK, any one can say a work. Can you detail what you said?

Sure, the formula for figuring out the dynamic forces on a wheeled vehicle includes the following components: center of gravity, weight of the vehicle, wheelbase of vehicle, height of components above ground level, acceleration or deceleration of the vehicle and a gravity constant.



While it seems like the size of the rear overhang won't make a difference in the handling of a vehicle, it does affect the forces the wheels experience because one component is the distance between the center of gravity and the axle ("d"). A large rear overhang moves the center of gravity toward the rear of a coach.
