Having purchased the '16 Greyhawk 29 MV last Feb '16. we rolled some 6000 miles from June to August of 2016 though out the west. At that time it was so obvious that steering was lacking.
The alignment had been done in March '16 and it worked some, but not nearly enough to make the coach behave properly.
Steering was a constant adjustment while travelling down the road, and even more so as wind and large trucks would push our coach all over the lane.
SO, Safe-T-Plus and Hellwig front sway bar was installed two weeks ago by Lafayette Spring (Lafayette, LA). We rolled 485 miles this weekend, and we found those two installed items to a be a "total success".
We had a serious head-wind on Friday as we headed north for 244 miles. The coach behaved "so much better" than it did previously. Steering adjustment was not an overwhelming constant issue like before. When winds would hit the coach, I found that the coach was stabile and steering was precise. Even as large trucks flew by, the coach was stabile. What a blessing that was.
I plan on having the rear Hellwig sway bar installed one day real soon.
