Factory Anti-Sway Question

The anti-sway feature on my '24 Limited is rated at 5klbs as I recall. My RV trailer weighs about 8klbs. I put air bags on it and it drives okay, without undue stress on the RV frame as with the bars. Has anyone experienced a problem with that?

 

Once you get up there to 5k tow, you really should be using a WDH vs bumper tow. Less squat, better handling and easier on the truck.

 

I towed ~8k in my Tundra. It was OK. As for anti-sway, it doesn't feel like Tundra has any. I had crosswinds on a downhill, felt a slight sway, and had to apply the trailer brake manually to stop the sway.
On the other hand, in my other vehicle (8k max-rated tow, so I was pushing it), you could feel the anti-sway kick in and try to compensate (I would say it was 50/50 successful. Manually applying trailer brakes always worked like a charm).

 

That's been my experience so far. Obviously no squat with air bags, and I doubt if there's more stress on the Tundra with just the factory receiver. Maybe there would be with a bumper hitch. I think the most stressful situation is with a wdh when the pickup is nosing up relative to the trailer. Of course I haven't put on a few hundred miles in a day, so I don't know how tiring that will be, compared to a wdh with anti-sway.
