Our Challenger handles fairly well but we installed a Roadmaster stabilizer after watching the horrific results of a front tire blowout. The objective was to help us stay safe in the event of a blowout. That event showed up for us Dec 27, 2017. Traveling down I-65 at about 67 MPH, we suddenly had a complete blowout of our passenger side front tire. I was able to steer us to the shoulder of the road without any further issues. The coach stayed absolutely under control.
I was later asked if I was sure it was the stabilizer that made the difference. Nope - I am not. I just know that I was under control the entire time. And the biggest problem I faced was getting a new tire. (Note: I have a TPMS installed and received no advanced notice of the blowout.)
As the only driver of our coach, I am responsible for the safety for all souls on board in this type of situation. (Note: We often have 5 grand children - that we love dearly - on board.) Would NOT leave home without the stabilizer.
I cannot say whether the stabilizer will help with normal handling but I darn sure can tell you (based on our experience) that it is well worth the $350 for emergency handling.
Take a look here at our report back on this situation:
