... I have been through the "Rear Leaf Spring TSB"
twice on a 2009 & 2010 Tacoma and the TSB is well worth the hassle. It took 3 attempts to get it done on the 2007 and it was done on the 2010 with no hassles.
I am waiting on the "2012 TSB Notice" on the 2012 now and when it is available, I will have it done. It is free and Toyota will realign all 4 wheels too and in some cases add bilsteins too. Make sure this (realignment) is done as it is sometimes forgotten.
IIRC, I saw the bill from dealer to Toyota corporate on this TSB and it was about $1,800.00 to do it.
The dealer does not add an extra leaf ... dealer will remove old 3 leaf pack and install a new 4 leaf pack.
It boils down to keep going back and "complaining about the harsh ride when vehicle is loaded"
(key words there) ... and getting the right dealer to approve it and order the parts and do it.
Some have zero problems with this TSB getting done and others have a hassle getting it done. Talking to right person at right dealer seems to be the key to getting it done ASAP.
Dealer will keep your truck a day and give you a free rental while the work is being performed and you should pay zero.
This TSB also improves handling, even when unloaded.
