I don’t have the auto leveling headlights. The needed one inch less sag comes from the 4”+ sag from the trailer tongue weight. I trusted the salesman when he told me the Platinum trim had everything I needed to pull my Ranger. There are three Toyota options that either of them would solve my problem, either the AVS (air suspension), auto headlight leveling or the TRD Off-road package (stiffer suspension). I didn’t spend enough time researching the Tundra trims and packages. The truck drives as smooth as butter and borders on being too soft of a ride.
