The frame issues were mainly related to the Gen1 Tundras, 2006 & older. I had a 2004 Sequoia (SUV version of the Tundra) and it was reviewed by the dealer for potential frame rust. No severe rust was found but they applied an undercoating on their dime. If it would have shown signs of heavy frame rust, Toyota would have replaced the frame on their dime.
We've had several Toyotas, including 3 Tundras. (Currently have a 2011 with 102k miles). Awesome trucks. Use it to tow our 8500# camper, which it does very well. (Rear looks loaded down in the pic with the camper, that's just a dip in the driveway...). I really couldn't ask for more out of a 1/2 ton truck.
