If too little caster exists, the car will wander and weave,

Too little positive caster creates a dead "do nothing" zone between left and right.
A typical mfg caster range is +2 to +5 degrees. This range can be described as:
+2.0 Degrees for 100% city driving.
+3.5 Degrees for 50% city and 50% highway
+5.0 Degrees for 100% highway driving.
E350/E450 Series RVs are 99.9% highway driven BUT are typically set to 3.5 degrees off the assembly line.
