 I got my SR5 4x4 access cab and loved it from day 1, and after a few months of driving and hitting a few little bumps on pavement & dirt roads (even while empty and just me driving) the rear end would bottom out and the suspension is less then standard. I couldn't be. that Toyota would allow only 2 leaf springs in the rear of any of their trucks. Otherwise the truck runs great & I think they have since upgraded this after 2006 - or at least I hope so. Everything else has been perfect.
