Hi, I am trying to find out the roll center of a truck's cab. I went over a similar thread in which jack action explained the concept of roll center. But I am having trouble applying it to something like the cab. It does not really have wheels or a multi-link suspension system like a car. The entire cabin is merely suspended on 4 coil-over-dampers and there's just 1 panhard rod to take care of the lateral motion. I am not even sure if this is to be modelled as a case of independent suspensions or dependent ones... Any help would be much appreciated!
