Got a malibu 23MXZ with about 5500lbs plus trailer 1500lbs. I've towed almost 1000 miles since I got this truck (2022 so all last season). It does just as well as my old F-150 platinum max tow package. Acceleration is better, braking actually feels better as well. Ride is about the same. With a good trailer there should be no sway. I've got 18 inch wheels on my trailer and it rides very smooth. Past boats had the trailer with (I believe) 15 inch wheels and upgrading those made a huge difference in tracking and sway. As for the truck, I added the timbrens and am looking at the bags if they ever release specific for gen 3. Right now, loaded, the truck will rest on the timbrens (as it's supposed to) so 1.5 inch sag. Ride is unaffected when not towing....except over big bumps or trying to get air! You will notice a more pronounced "bounce" in the back. I had a sag of an inch on my old truck as well. I used bags on it and really liked them. Hope this helps.
