Tailgate woes
 Beware loading tailgates on new crewcabs. I loaded 12 yard blocks for retaining walls (16# each) on the tailgate and crawled in the back to move them forward.  This action pushed an internal tailgate beam sandwiched between inner and outer panels out. The movement made four very obvious reverse dimples on the outside of the tailgate. Toyota factory reps. said I had overloaded the tailgate and offered no resolution.  I found no tailgate load rating in the owners manual. This tailgate is a new taller design for the crewcabs due to Sequoia based frame and body according to the factory reps. Tundras are not truck material in my opinion. Factory service needs improvement. No more Toyota 'trucks'.
