Long time 4x4 owner but new to Toyota's. I've had my red '07 DC SR5 Tacoma 4x4 for all of 5 days now, which I bought used, and really love it.
Was a bit nervous at first though: 2nd day I was hauling what I thought would be a 'light' load for a truck with 1/2 ton rating, a few bags of landscape rock, and wow was I disappointed! It bottomed like a saggy-back Ranger at 100k. I thought the springs were broke at only 16k miles! Then I found out about the suspension TSB by browsing TN, took it to the local dealer and confirmed it's still in warranty. They are ordering parts now!
Thanks a lot to the TN, it's great to have a community of owners to share experiences with. We're all richer because of it!.
