Test Drove 2 TRDs

I am not abusing my truck, or jumping with it. I am 59 years old and more responsible than that. In normal driving, on paved roads, hitting a bump, such as a pot hole or speed bump (with cargo or passengers) is when it bottomed-out (I said this before). My new 2001 did not do this for its entire 136,000 miles and my new 2010 did not until about 70,000 miles, only my new (10 miles) 2005 from the very start.
