I'm in the same boat Steve,
I'm in the same boat Steve, waiting on call from dealer that new frame is in. Lots of success (and horror) stories on this site. I for one will not feel at ease until I have it done, and then I will gladly post about it. My understanding is that Toyota is treating the frame replacement as a service bulletin item, not an official recall, on Tacomas manufactured from 2005-2008, irrespective of mileage. (I guess the frames have thicker/stronger/better paint coating on the 2009+ models). I am also pretty leary of having my dealer tack on extra work, as to my knowledge my truck is up to date with repairs and as solid as a rock at 135k. Smelling a possible skunk, I contacted my Toyota zone representative (SE here in Fla) and he gave me the name of the service manager at my dealer. He said I should make an appointment to have the manager show me exactly where the rust problem is on my truck in advance of any work done, also any other perceived problem areas that may require attention along the way. He said in order for any Tacoma to qualify for the frame replacement, there would need to be at least a 10mm rusted section that could be perforated. He said my dealer (Autonation in Orlando) has a pretty clean record as far as complaints, but that I could call him back if any problems arise. I do plan on letting the dealer know I will be posting my results. Hope that helps.
In advance of the work, I plan to contact my dealerships
