I am almost 100% sure the rust issue was extended to the 2001 through 2004 tacoma's as well. I know there is a TON of info on here about the frame rust issue so just do a search of some key words and the stuff other members have posted should come up. There is info all about the options and the experiences guys have had with it. I know there is a coating that you can have applied by Toyota for free if you live within a certain area or state and I guess that is supposed to help. Heard its kinda like slime grease type thing that takes a few days to actually set up on the frame.
