I have a 03 Ac tundra with the trd package. I am going to sell my truck and buy a 05 tundra dc black 4x4. THe problem is not only am I haveing a problem finding a 2005 black dc in my budget with around 50 k miles. I find it even harder to find one with the trd package. So it is really that big of a deal? I plan on updating the front shocks to the 5100's in the front- and possible an air assit system in the rear. So is there anything else the trd package offers that I will notice comming from my previous 03 trd ac?
