I have a 2014 Silverado Z71 double cab that when towing my tt sags if I load some extra camping gear (bikes,firewood,canopies) just some added items. My question is what type of addition is recommende...
After towing with a half ton at 0-500 pounds over GVWR, I think rear suspension aids at best complicate WDH adjustment and mask overloaded rear axles and GVWR. My truck never looked overweight with WDH and it towed comfortably at 75mph if I wanted. Spend $15 at a CAT scale before $200 on suspension aids to fully understand your loaded weights against all your ratings. May want to fine tune that WDH too.
