Have others had the same experience?

What is your question?

I live in the northeast - and the frame, undercarriage, and suspension corrosion on my 2003 land cruiser is unacceptable. With Toyota replacing so many other frames (Tacoma, etc.) in this same timeframe, I'd like to know if there are enough 1998 - 2007 land cruiser owners out there to justify class action or another approach.
