Bounce is definitely an issue, especially with 110 PSI tire pressure. I'm contemplating a suspension upgrade to include shocks.

I always considered adding shocks but we just don't get all that much bounce, atleast that I can tell.
I wish I had the link but there is a video on youtube of a trailer's undercarriage and suspension & you would not believe the movement and oscillation of the shackles. Almost sickening. Shocks have to help.

Yes sir, I saw that video. That's why I started researching suspension upgrades. As fast as that equalizer was bucking it's no wonder the bushings wear out so fast.

Isolating the axles from each other eliminates the equalizer. So the Liberty Rider slipper spring system has caught my attention.

I'm aware of the Timbren axleless devices but still willing to stay with leaf springs on my 7K axles.

Yes! That's the video. I have I'll equipped 2600# springs but considering swapping in 3500 springs and shocks. The old springs are starting to flatten out a bit.
The ultimate ride I think would be an independent, maybe torsion, with shocks and disk brakes. Eh, maybe on the next 5er we will get that.

With all that said, I do love the Trailair. Just watching that adjusting to the bumps going down the road is enough to know it's doing something. About 65 psi is good for me. Plus about 10psi in the airlift airbags and it rides smooth.

For example, if you have roughly 12,000# on the RV axles...or about 3,000# on each tire, the tire load chart may very well call for less pressure.


I have dropped the air pressure down to one hundred psi and still canít tell any difference. I may try the Goodyear Endurance next time

100 psi MAY still be significantly high.

The load chart will give a really good idea of the proper pressure for your specific tires with your loading. Ideally, weigh the rig to get the actual axle weights.

I had to go over 100 psi on originally installed 18,000 lb. Trailair, to hit the arrows correctly. And it was so tight it wasn't doing what it was supposed to do. So I had the next biggest size bladders installed, the ones that go on the 21,000 lb. model, and it made a world of difference. I hit 93 lbs and it's perfect.

I've noticed the trailair bladder is bigger on our 2019 CC 34RL2 than what was on our 2009 32 WRL Silverback. Last time I measured the bag was 90PSI and very near the arrow mark.

I do need to add air every few weeks.

Liked the first one which is why we made sure our new trailer has it.

They offer 2 sizes, an 18k and a 21k pound unit. You must have the 21k on the new 5er.
