I took it to the dealer, and they say Nothing is wrong with the truck.

Expert Reply:
The 2020 Ram 1500 has rear coil springs which have a tendency to cause sag while towing or hauling. Therefore, I recommend adding suspension enhancements to combat this and also work to improve sway control. The SumoSprings Solo Custom Helper Springs part # SSR-307-47 would be a great option for this and they retain factory ride quality during normal driving conditions.
I recommend adding the SumoSprings and if the desired sag and sway reduction is not achieved you can look into weight distribution.
