We had a Safe T Plus Steering stabilzer put on our 2006 Alpine by Redland Truck Service in 2009 and have put about 12,000 miles on it since. They also did the motion control units at the same time. We found a big difference in driver fatigue as a result of the Safe-T-Plus; just don't get as tired driving it in the day because we're not fighting the little movements needed in the wheel all day, especially in side winds and trucks passing us. I have found I can drive farther in a day as a result of installing it, and I think it was more valuable than the motion control units on the airbags.
The one thing you will notice that turning the steering wheel when going around a corner at any speed takes more effort, especially when you're going down the freeway and have a good bend in the road. It's not a great amount of pressure, but the lateral forces (like G forces), need a little more effort to make the wheel turn than they did otherwise. That said, it does reduce driver fatigue.
We installed it because of the concern over the steering box, which we subsequently repaired in Junction City at Carrier and Sons, and with concern about front tire blowout, but as others, like Basil Shannon has said, don't cause a great deal of pull anyway in Alpines. So I would say I wouldn't install one for a front tire blowout concern; just for reduced driver fatigue and better control in sidewinds.
