I am looking to purchase a Roadmaster Reflex Steering Stabilizer for Class A Motor Homes. I want to make sure I am purchasing the correct items. I have a 2019 Winnebago Horizon 43 class A motorhome on a Freightliner chasis.

Got ya Mark, thanks for reaching out!

The Roadmaster Reflex Steering Stabilizer for Class A Motorhomes is the correct part for the Horizon but there two parts, the steering stabilizer itself # RM-RSSA and a vehicle specific mounting bracket kit.

So we’ll want to confirm which Freightliner chassis your coach has before recommending the correct kit.

The easiest way to verify this is the Freightliner chassis VIN
or the chassis information from the data plate near the driver seat area.

Once we have that information, we can make sure you get the correct stabilizer and matching bracket kit for your motorhome.

Do you flat tow with the Horizon or just driving the coach only?

@RayW thanks for the feedback, most are surprised how much the Reflex helps with the overall control once it’s installed and they're out on the road. appreciate you choosing etrailer!

Hi Mark, this steering stabilizer made all the difference for me. No more fighting the wheel to stay in lane. It used to take two hands to drive my RV Fleetwood Flair 31a and after a long drive I felt like I'd been wrestling all day. Now I can drive with one hand and be comfortable, after long drive now I arrive no different than driving a car. Good luck, you will enjoy
