Airbags Vs Sumosprings vs your advise

2018 5.7L Crewmax 2WD TRD Sport Max Towing Capacity 10,300 Rig 2021 Grand Design Transcend Max weight loaded 7,500 lbs. Husky Weight Distribution System My Truck tows my rig extremely well. I tow in south Florida with no real plans of ever going north or Ocala and I typically tow to the Keys. I do experience a little more squat sometimes than I would like to. What would you recommend adding for support in the back end. Thank you for your help and input.
