I installed a Safe-T-Plus steering stabilizer at Redlands Truck and RV last year because I was worried about the pull from a front tire blowout like you had, if my wife was driving the coach with her rheumatoid arthritis issues. I also was worried about the steering gear box bracket, which I subsequently fixed at Carrier and Sons. So far I've been lucky on both of these issues and haven't needed the steering stabilizer for those reasons.
However, shortly after I installed the steering stabilizer at Redlands last year we drove to Georgetown, Texas, 1300 from Palm Springs miles in 3 days, as we have done at least 3 times previously in the coach. I was amazed at how much less tired I felt every day. Since then, I've noticed it every day I have to drive 400+ miles. Its just less tiring to drive; I think because the steering wheel corrections are just fewer, not as hard, and the coach tends to wander less. I didn't expect the reduction in driving fatigue. It does as EMike says; tends to take a little more pressure to turn at speed on the freeway. I have also hooked an asphalt drop off a couple times, and it definitely doesn't pull as hard. I also believe it doesn't jerk to the side as much when I get passed by a truck in a strong crosswind.
So for me the hidden benefit was a reduction in driving fatigue along with the feeling of more control over the coach, especially when it's jerked sideways for any reason; a front tire blowout potentially one of them.
