Sumos or Sway bar

rgatijnet1 adds a good point that air bags is another option. I like having more control over the settings and don't mind extra installation components. But, are airbags obsolete?

I haven't looked extensively, but I don't see sizes for airbags after about 2012 (per Airlift website). Similar results at reseller websites.

From what I see, there are active comments & videos about Sumo Springs and lots of purchase options. Air bags have few comments / videos and the purchase options don't exactly jump out.

So, maybe airbags are "old school" and sumo springs are the way to go?

Rear or all four air bags are also another thing that will minimize sway. The air bags also have the ability to adjust the air pressure according to conditions. I have four corner air bags which allow me to continue driving in some fairly high cross winds just by airing them up to 90 PSI. When the winds are light, I lower the pressure down to 20-30 psi for a smoother ride. They also allow me to raise the rear end of the coach a few inches when I need extra clearance to get in to my steep driveway. All of this is done with a push button on the dash that can raise or lower the air pressure as I drive. After using the air bags for 50,000+ miles, I have no need to add SumoSprings or a track bar with the air bags. This is on a Workhorse W22 chassis so the air bags may or may not do the same thing on a Ford chassis.

I have installed Timbrens before and I did not have to remove any wheels/tires. There is enough room to install them from underneath and the inside to not have to remove the tires. As for track bars, I seem to get more wag with the toad on the back than without it. The little amount of play in the receiver hitch, tow bar movable joints and the attachment to the toad, all add up to a bit of movement from the toad, following the road surface. I have tried to eliminate the movement by tightening the joints, but you cannot move the tow bar, and the you can feel the toad pulling at the back with it that tight.

Lots of good information here, although much of it is not quite on-topic according to the OP's topic title. I appreciate gutfelt's clarification of the purpose of a rear track bar vs sway bar.

As for track bars, I would guess that it would be especially suitable when towing a car. The car can be a very big tail that wags the dog. Maybe someone could confirm this?

When you focus ONLY on reducing lean, the choices (mostly) are adding larger sway bars or Sumo springs. Both choices are similar costs. It sounds like Sumo is the better choice.

How abut DIY install of these options at home? I could install the bars myself, but the Sumos require the wheels off. Not sure I want to remove wheels in front of my house.

I put a rear sway bar on along with the CHF and the safety steer. I also had an alignment done. At the time of alignment the safety steer was left loose. and after the alignment before the alignment equipment was taken off, the safety steer was reconnected. A big difference indeed. In the future I will most likely add the Sumo springs as well as Koni shocks.
I had many people point me toward the rear track bar but I felt the problem stemmed from body roll and sway which really said go with the Sway bar.

Really....Explain that to me please.

A rear track bar keeps the rear axle from shifting side-to-side, noticeable when driving in a straight line. "The tail wagging the dog" is how it's described.

A sway bar limits how far the motorhome will lean when cornering or swerving.

Since the original post I have installed front and rear Sumos and a rear sway bar..also have a safe t steer..U am pleased with these additions.If I hit the lottery I will also add front sway bar. The rear one made a huge difference.only thing I am not 100% pleased with is the safe t steer. Can't seem to get it set just right.

sounds good as that's what a sway bar is designed to do "eliminate sway" I think sumos are a great addition in addition to a ASB system

One way to adjust it is to set up a cardboard piece on the dash so that you can drive down the road and put a mark when it is tracking straight.
Then you park the rig, lift the front wheels off the ground with the levelers and adjust the Safe-T-Steer to center the wheel on the mark that you made. This sure beats the trial and error method.

Terry, try to get someone to follow you when you are having trouble steering. Have them look to see if the rear of the MH is moving side to side. This is what usually is happening with straight ahead steering problems.
