Wheelbase to length ratio. What does it mean?

Wheelbase to length ratio has more of an effect on ride than on handling. Plain old wheelbase has more of an effect on handling. A long wheelbase will make the vehicle more stable but will make it harder to handle in tight turns, like in a city or getting into a camp-site. The long wheel base makes the rear wheels track farther inside of the front wheels, and usually ends up with a larger turning radius. From a ride perspective a long wheelbase to length ratio puts the rear wheels farther back and the front wheels farther forward and the vehicle tends to ride more smoothly. A short wheelbase to length ratio puts the rear wheels farther forward and you tend to get a rocking-chair effect that can be quite dramatic at the very back of the vehicle. Pusher Class A-s usually have the longer wheelbase and wheelbase to length ratio and are known for a smoother ride. Front engine Class A's are the ones that often have a long overhang behind the rear axle, might handle better in tight quarters, are a little less stable on the highway and tend to ride choppier, particularly for passengers who might be at the back of the bus...
