I have a 2009 DCSB TRD Off Road 4x4 and compared to the 98 Tacoma I had 10 years ago the quality isn't as good. Dont get me wrong I do love my taco but the truck doesn't feel as solid as the 1st gens. I would buy a Tacoma over any other mid size being made today. You have to have the TRD off road package to get the rear E-locker. If you have any other questions let me know.
'09-'10 with auto tranny were subject to the delayed shifting problem. Can be corrected some what through a tsb-covered reprogram. I don't know if 2011 models were affected as well.
Don't bother with the "sport-package" unless you absolutely must have the non-functioning hood scoop.
