24.1

Just letting you know what we did with our 2016 24.1 Axis. Front Sumo Springs, Saf-T-Plus (Yes, I got another one for our SOB because I like them so much) and Koni shocks all the way around. Did much better on the bridge transitions and the truck passing. Bad winds with the short wheelbase will still be bad.

On my Axis 24.1 I added Safety Plus and they recommended changing the caster when they checked the alignment. Donít know which helped the most but it certainly is a pleasure to drive now. Can even pass large trucks one handed.

The most noticeable driving improvement on a 24.1 is an alignment with caster change. The caster mod increases the total alignment cost, but once itís done all other stabilizing and sway mods will greatly improve overall ride.

Itís unfortunate that Thor does not make the appropriate alignment mods at the factory once the box is added to the Ford chassis.

I'm now researching Continental "VanContact" all season tires with a 120 load index; they are marked as C225/75 R16, made for the Euro vans evidently. Some of the wallow in these is from the tires, a steel belted with a stiffer sidewalls would help. I'll stay with 225/75 R16s .

Like others I also an alignment shop fix the steering... That provided additional handling, braking, and sway control capability.

I would really like for it to steer and ride better, but I worry about spending thousands and thousands of dollars to end up with only "marginally" better.

What exactly have you done and what % better would you estimate each of the upgrades and then in total?

I have a 2016 29M and have only done the CHF. Am thinking I will add the Safe-T-Plus to help with the steering. The ride is pretty harsh, but then the roads here in CA are crap so . . . . I'm somewhat of the opinion that nothing is going to make a big truck, motorhome, whatever ride smooth when your roads are complete crap.

Just don't want to waste time and $$$$$$$$ if I have to wonder whether the upgrades actually made a difference or not.

Thanks for any info you feel like sharing!!!
Here us everything I did to my 29m. Front end alignment, fully loaded weight on a Cat scale to get weights for correct tire pressures, CHF front and rear, saf t plus, front sumos. Before any of these were done I felt the coach was undrivable as delivered from the factory. I joined this forum and got loads of info for handling improvements and took what I thought was a budget minded methodical approach. The first three things made the coach easy to drive, but it still wore me out after 200 miles or so. The last things make the coach enjoyable to drive and I could go all day if I chose to do that.

I've done all these also and the rear track bar. For me the track bar was the best improvement

Iíll do the steering stabilizer because I already have it from a previous coach and the CHF, because itís ďCĒ but Ií donít really consider any of it essential. I put front Sumos on my last F53 coach and found the benefit to be negligible and certainly not worth the $500 price tag (self installed). The available changes DO make for a less tiring drive but itís a truck after all and it drives like one. You can be safe and enjoy the life without any upgrades. You get used to it as delivered.

Thanks for the info!

Iím going to add the Safe T Plus for sure, see how I like it.

What tire pressure did you end up at?

Also curious for all you other 29m owners, does your front driver side lean down?

What exactly is this caster change you mention? Can this be done on the F53 chassis with positive results also?

What exactly would I ask my alignment shop to do for this caster change?

What track bar did you get/install on the rear?

I followed your recommendation a while back on the Ready Brake hitch and have been very happy with it btw.

It's been widely discussed that the caster must be changed on an E350/450 to: -5.1 degrees on driver side and -5.3 on passenger side

Not sure what the specs are for F53

Suggest that you use search function on this website and on Google.

Taking an inventory of mods I've seen on this thread. I've noticed everyone has a favorite related to what makes the boat on wheels feel less like a boat on wheels.

-Sway Bars
-Steering Stabilizer
-Track bars
-Sumo Springs
-Air bags
-Bilstein or Koni shocks
-Caster modification
-Alignment (not a mod but related work)
-CHF - not sure what this is (Congestive Heart Failure?) - need an acronym index

And the winner is...
I'm starting with steering stabilizer and sway bars as they seem the most common mods. Either that or pick it raffle style.

Just a thought and maybe a thoughtless thought:
Does a steering damper simply mask the problem where a bar system, be it track bar or antisway bar/torsion bar, actually cure parts of the problem?

I don't see how a damper does anything except dampen feedback to the driver.

Don't get me wrong; I have a damper. It's not a cure, it's a fatigue lessener.
I believe in them, I don't believe they fix any sway. They aren't attached to the body, they aren't attached to the frame rails, they don't attach the body with the frame rails(the flexible parts of the frame).

If dampers do fix sway, how?

CHF = Cheap Handling Fix and Iíd sure do that before Iíd spend hundreds of dollars on new sway bars. Itís free and you can do it yourself if youíre ďhandyĒ. Do a search for instructions. As much as has been posted about the CHF and replacement bars Iíve NEVER read about anyone who did the former followed by the latter and reported it to be worth it.

Chf

Since the CHF is only applicable to the F53 chassis, not the E450/350, I would start with weighing the rig for proper inflations, alignment/casters and the Saf-T-Plus which is not a true steering dampener but a return to center device. I emphatically also suggest rather than taking a poll, you deal with a reputable RV/truck service center and tell them what your specific rig is doing during the drive that you do not like. Not Camping World.
