Hello,
Following this. Same problem. 2021 Sierra Denali with quite a bit of sag towing our camper with about a 700 pound tongue weight. Camper weighs 5800 pounds. Looked into airbags as well but won't fit with the adaptive ride control. Has anyone found a solution to this, or airbags that would fit?
LikeARock - did you find a solution that would work for you?
