Do I need sway control on my trailer if my truck has TSC?

[road_freedom]

My 2019 GMC Canyon has TSC (trailer sway control) as part of the StabiliTrak system. I'm curious as to whether it will be sufficient for my needs. I'll be towing about half my tow rating and about 75% of my TV mass.
Is anyone's TV with these TSC's (they're common across all manufacturers) using sway control on their trailers as well?

Thanks

Thanks to everyone who replied. I'll be using my Equal-i-zer WDH with sway control for sure.

I turned my trucks sway control off on my 16, F250. I found it over reacted when I was towing our old 30WB work and play while using the Blue Ox sway hitch.

This is not true for safety equipment, like sway control. Sway control is for when things get dicey. Things may not get dicey on "a short run camp trip."

Huh? You can see how the trailer reacts to induced sway or a semi in short order if that’s the purpose of the “trip.”

Can’t imagine putting a wdh and sway on a 2 ton trailer behind a new Colorado but instead of asking why not just take it for a drive and form your own opinion.
Opinions here will be everything from you’re fine as is to you need a dually with a Hensley arrow.

Depends on how much instability you are willing to tolerate. The TSC system REACTS to sway as soon as it senses it. It takes the computer just a few milliseconds to identify the sway and then to apply corrective braking. The sway control on a WDH tries to PREVENT sway from starting in the first place so the TSC doesn't have to REACT to it. After pulling my TT with my Canyon for 30K miles in 4 yrs. I can feel that "uncomfortable" instability whenever I'm following a semi or in buffeting cross winds and forgot to engage the sway control on my WDH.

The TSC working with the sway control of my WDH saved my a$$ a few times when I had to do a high speed swerve to avoid road debris on wet roads. I strongly recommend you get a good sway control WDH to work with your TSC!

If it's the same as the F150's "sway control", then NO, it's not a substitute for a hitch WD/sway control device...

In my F150's case, it only comes into play when your truck really, really starts to sway.. Like see sawing the steering wheel kind of sway.

You will need at the minimum a WD hitch just to help level you out and put some weight back to your front axle.

Good luck! Mitch
