Keeping It Between the Mayo and Mustard: Our Roadmaster RV Steering Stabilizer Review


This summer we were in Vancouver, Washington visiting the Roadmaster factory where they manufacture almost every component they sell. While we were taking a tour, we got to talking about their Reflex RV Steering Stabilizer. They suggested we let them install one and see how it works. Hmm…something that could make driving the motorhome easier? Of course we said yes!



Here are our thoughts:

We went from a 40ft diesel RV on a Freightliner chassis to a 30ft gas RV on a Ford f53 chassis. For the most part, this has been just fine. We have all the space and power we need, but there are a few places where I miss the luxuries of the diesel. The steering is one of the big ones. The long diesel motorhome seemed to naturally want to track straight down the road while the shorter gas motorhome has a little more play in the steering wheel. It seemed I was always having to make small corrections to the wheels between the mayo and the mustard (between the white and yellow stripes – thanks @LifesaTripp for that saying!)

What is an RV Steering Stabilizer?

The RV steering stabilizer is really pretty simple. It’s just a spring around a shock absorber. It attaches to the front steering Tie Rod and to the Axle. The Reflex RV Steering Stabilizer helps to take that play out of the steering system by adding a little resistance. The spring wants to always pull the wheels back to center and the shock absorber helps to smooth out the steering inputs. When you turn left, the spring is pulling back right and when you turn right, it is pulling back left. Pretty simple! When you hit a bump, ride in a rut, or go off the edge of the pavement a little, the shock absorber inside the spring helps to keep the wheels from getting pushed around.

Roadmaster even says that in the event of a blowout, the steering stabilizer will help you retain control of the motorhome. The RV steering stabilizer will resist the tendency of the front end to turn towards the blown tire. Sorry, but we aren’t planning to test that feature for you ????

The installation actually went so quickly that we missed getting photos or video of it. All they had to do was make sure the front wheels were pointed straight ahead and bolt it up. They install these all the time, so I am sure that helps. Still, I wouldn’t hesitate to try installing the stabilizer myself. (I might still end up at the shop, but at least I could say I tried!)

In the driver’s seat, the steering wheel feels more solid. It doesn’t feel as wishy-washy as before. Now, it’s much easier to drive comfortably with one hand on the wheel. I’m not so tired from having to constantly adjust to keep the motorhome on course at the end of the driving day.

Large gusts of wind and semis passing don’t feel like they are going to blow me off the road. On smaller country roads where the motorhome is as wide as the lane and there is no shoulder, the stabilizer makes driving a lot less stressful.

If you are in the Oregon and Washington area, make sure to check out some of the awesome Harvest Hosts. We ate so many blueberries at this one!


Do you need this? No…

If your motorhome is in good shape and your tires are properly inflated, aligned, etc., then you will be fine.

But if you are on the road as much as we are, this really can make a big difference. I’m definitely not going to take it off.  And if I get another similar sized RV in the future, I will add an RV steering stabilizer to it.

    We have been looking at RVs now for three full years and have come to the conclusion that the Newmar Bay Starr 3113 is in the running. Our barndominum will be completed this year. How do you like your Bay Starr?

      We’ve been very happy with the Bay Star. The size fits us and we’ve had no major problems.

    I have a brand new 2018 THOR Windsport 29M on a Ford F53 chassis (looks very similar to your rig) and am disappointed at the effort needed to keep it between the lines, as you reflected. I’m a good driver but this thing keeps me constantly busy staying in my lane. The steering is not sloppy or loose, the rig just wants to wander, needing constant correction. I’ll have the alignment checked and possibly a steering damper installed based on your review.

      Yeah, these gas rvs on leaf springs can take a bit more effort to drive.

      Think about the sway bars too. It might not seem obvious, but every-time your RV rocks from once side to the other it changes the steering geometry a little bit and the wind forces on the RV. So, controlling the left to right rocking of the RV helps a lot to control the RV overall. We noticed the largest improvement after the sway bars.

    What tire pressures have you found to work well?
