Hi underfire,
but didn't get that severe gusting effect on full motion. We did get sideways, but I don't remember the ac rolling around like that.
I'm glad you notice the same limitations also.
Since the sim motion is limited to the amount of travel of the jacks, and at full jack extension / retraction the sim motion must approach zero - then it can't faithfully imitate real life. Your sideways acceleration is simulated by rolling (banking) the cab but at the same time keeping strong visual clues to being level. It sounds like you can sense the sim cab rolling also. Glad I'm not alone.
