I will have to say the best thing I've done is add the Henderson rear trac bar for what you are talking about. Our last trip was the first time I had it on our 3010 and I'll have to say what a huge difference. Every time I could see an 18 wheeler approaching I would get ready for the back end to start to wag and it never did. It was a 4 hour trip with plenty of vehicles passing us and not once did I feel the usual wind effects of any type of vehicle. I also added the safe t plus to the steering, but didn't notice a big difference with that. When it wasn't windy conditions driving I thought the back and forth steering seemed less, but on the way back on our trip it was an extreme cross wind and I had counter steer a lot. I think they make an add on to center the steering from inside the cab in those conditions, but I didn't purchase that yet. But again, for what you're talking about the rear trac bar is exactly what will take care of the tail wag with vehicles going by.
