Given the perspectives thus far, I wonder if the difference Richard noticed withe the truck is also due to wheelbase length. The shorter it is the less steer input is needed to establish a change in vehicle angle to the road. Maybe the difference is that the corrections are not so much less frequent in the trucks and cars as they are proportionately smaller based upon wheelbase. This explanation would be consistent with the reported behavior of Prevost and reports that our coaches tend to go straight in flat road no wind conditions. I've experienced this with both my coaches AND complained about wander.

We can't change wheelbase, but we might consider reducing the diameter of the steering wheel. That would deuce the distance our hands travel to achieve an angular input.

One other thing I've noticed is that when I consciously slow down the speed and frequency of steer inputs the coach behaves better. This would be consistent with Richard's wondering about the effect of our forward sitting position.

I'm beginning g to talk myself into the perspective that most of our coaches are fine, the problem is mostly the result of how our brains interpreted the sensations produced by the configuration of our coaches.
