Steering stabilizer is a GREAT add. Helps the steering staying centered in normal driving but in a the event of a blowout it can be a lifesaver. We had our Roadmaster Steering Stablizer installed soon after buying our coach. We now 52k+ miles on our coach and one front wheel blowout behind us. Our coach handles really well and in the event of the blowout we can attest to how much it helps to keep the coach moving straight ahead.
No problems with stressing the power steering (that we are aware of).
This is a link to our recounting of the blowout.
