2023 GMC Sierra 1500 AT4 — trailer feels nervous in crosswinds

Owner notes beat generic advice here. On the 2023 GMC Sierra 1500 in Detroit, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “trailer feels nervous in crosswinds,” that was the fork that mattered for me. Verbal 'we'll take care of it' is not a plan. Climate here is different, so treat that as a local data point. I'd rather look cautious in this thread than stuck later.

I'd keep this practical. Verify the cheap/easy branch on the 2023 GMC Sierra 1500 before a big repair or a big spend. I'd do that before spending real money. Not gospel, but it saved me a headache. I've seen both outcomes, which is why I'd test instead of assume. This is me being the wet blanket on purpose.

Write down what you already tried. A second data point from another 2023 GMC Sierra 1500 owner helps more than a generic diagnosis. I'd do that before spending real money. The universe charges extra for guessing. Might be overthinking it, but I'd rather overthink than overspend.

I parked the 2023 GMC Sierra 1500 and wrote down what I already tested so I'm not repeating myself. I'm in no rush to be a hero on it.
