Almost every post complaining about the Tundra's bouncing is about 4X4s or TRDs. My impression of the TRD was not favorable on hard roads, I don't think it's very comfortable on the bumps in the freeway. I'm assuming Toyota designed the shocks to be beat by country roads.
Maybe most of my skepticism is misdirected, could it be the off road trucks are the animals that are being unruly on pavement?
