Steer Safe or Davis Tru Trac Bar

Anyone had any experience with Davis Tru Trac Bar or Steer Safe. I have a 1999 Four Winds Majestic M30Q motorhome on a F53 Ford Chassis, V-10 motor? Would like a little better tracking of the MH on the road. Do these really work and which might be best to use? First Class A motorhome.

I just installed a rear track bar (neither of the above, which are different creatures) on my Southwind, tamed the wiggle pretty well. Do a search, there're a zillion threads on this very subject. It depends on what the problem you're looking to fix is.

TruTrac is a front track bar, I believe, and steer safe is a system to help keep the front wheels pointed forwards.

MajesticRV, Quite honestly you might want to consider using both of these "types" of devices concurrently.

I use a Davis Tru-Trak (no longer in business) and a Safe-T-Plus (STP). Both of these devices work in tandem. One from the steering wheel down and the other from the bottom of the tires up. Reducing the effects of rut tracking with the STP and eliminating push using a track bar makes for a relaxing day! Of course this is enhanced with a good set of shock absorbers as well.

On our smal T-28 Bounder, 99 F53 chassis, we did the following:
-4 corner weight, and tire PSI set to Tire manufacturer spec
-Urethane bushings all around
-FSD's front, adjustable on setting 2 rear
-Front and Rear Super Steer
-Bigger rear IPD sway bar
-Safety-T-Plus
-Air tabs

I looked at Safety-T-Plus as a emergency tire blow out aid, but it also helped on steering corrections reduction.

Much of the other items were too much. I'd suggest the fee stuff first. The Safety-T-Plus (or the springs, as they are both good for tire blow out). I would do the rear SS only. Check all bushings, replace if needed. Air Tabs (the last thing we did, and the least expensive. It really helps in shifting cross winds, and when trucks go by).

Then go drive it and see how things go.... You can always spend more money, but suspect you will stop before going as far as I did!

We like our Country Coach now, but sure miss that little T-28, with Banks and handling - it was a fun safe secure ride!

Best of luck,
Smitty

Those two devices do different things, so you may want one, the other, or both.

The track bar stops side play in the suspension, which typically stops erratic steering problems or the feeling the tail of the coach is pushing the front end around. Steer Safe and similar Safe-T-Plus are for emergency handling, such a tire blow out of running off a low shoulder. They help you keep the steering wheel straight.

Majestic,

Here's a link to my thoughts about these devices.

Steering assist devices---another happy user

If I'm reading your coach's model number correctly, you have a 30 footer. Mine is just about 31 feet. The wheel base is approximately 20 foot (pretty short), with an extra 10 feet of overhang in the rear. That overhang acts as a big fulcrum as soon as any sidewind or pressure wave from a passing truck hits it, making it difficult to maintain a straight heading. The Steer Safe and rear Ultratrac additions I installed made a huge difference in handling, and mine was already aligned, balanced for weight and had proper tire pressure for the load.

I had a 2007 Fleetwood fiesta 31ft (workhorse chassis) Installed steer safe and a tru-trac bar. Made a tremendous difference and was really worth it! I was able to drive safely through a sandstorm in Bqkersfield while others had to pull off. In normal use it was one finger steering including passing and being passed. I am currentl\y using steer safe on on my 35ft DP, I took off off the Safe T Plus.

Roadmaster has the davistuetrac.
I have a 33' f53 chasis with the truetrac. I love the side to side control
koni fsd ; love the higher speed handling and how it smooths out
Heavier sway bar; helps with the backend.
Best bang for the buck though was alignment (canter) and knowing my weight capacity on the front axle and loading it up to help put some weight up there. Oh yea, tire pressure is important, and for me i am at 80 in the front and 86 in the back on TOYO commercial tires (which are ok, just a little bit stiffer due to the casings)

Thanks, Michael, for the feedback on my steering and handling questions. My motorhome does pretty well on tne interstate even when passed by large trucks, but I have not been caught in severe cross winds and that is what really concerns me.
Regards,
Randy Kornegay, Montgomery, al.

I put the Steer Safe on my old P-30 Pace Arrow 1990 and it was great, easy install and a great improvement in handling !!

I have both of them installed on my rig. I have a 35 foot Safari Simba on a Workhorse W-22 chassis. Both items are sold by Roadmaster, through distribution. These products helped some. However, I still have the tail wagging the dog and a swaying issue. I was told by Brazel's in Centrailia WA, that I should have started with the rear end first then work forward to correct any handling issues. I've read a lot of threads in an attempt to find an answer. I'm tired of pouring money into the rig. It's difficult to sort out the data between the sales pitches from the RV suppliers and the users not wanting to admit they purchased some snake oil.

kfr9113, I can state this without any hesitation or any other purpose other than to pass on my 1st hand experience. Suspension modifications done piecemeal should be applied to the "rear" of the motorhome first. No snake oil and no sales pitch. I've been writing about this for 10 years and it's what works for me and many other members here in the Workhorse forum.

I was so captured by the performance of the rear that not doing the front with a Tru-Trak and Safe-T-Plus would have to this day leaving me wanting for more.

The rear of the vehicle is the end of the motorhome that is the most effected by overhang. If you look at the body in terms of distance from the fulcrum, which I place directly under the driver's seat, you will see that the moment arm from the rear of the motorhome to the front is on the order of 10+ times more than the distance than from the front axle to the driver's seat.

A little bit of a push on the back of the box will translate into a a big push at the fulcrum. Ask Archimedes. Example is being passed from the rear by a high speed large vehicles. This pass will impart a large amount of force on the box which will cause all types of necessary steering corrections.

Getting passed from the front by the same large vehicle will impart a shorter duration push but not so much that it requires a lot steering input to correct. The distance to the fulcrum is a lot shorter and as such does not magnify the moment as severely.

If you only budget for one item per year, the next item would be a Ultra-Trak for the rear of your motorhome. Following that, a nice set of shocks will round out the suspension mods quite nicely.

Davis Tru Trac Bar
Had it installed when I got new tires and shocks. For better tracking, less sway from road and other vehicles. Drives like a big SUV.
