My 4wd car (honda crv) is too light on its chassis with a single driver occupant, so i keep 4 bags of cement in the back during winter time that the chassis behave better. This i've had to do with many cars/trucks over the years, and mostly because the designers of those vehicles had to design for a static loading weight... and single-driver is lower than that weight.
The idea is to calibrate the suspension to measure the vehicle weight on start, and then to adjust the anti-roll torque and the shock absorber pressure to accomodate the ACTUAL vehicle weight thereby achieving an ideal ride and load safety.
