Having come from a Toyota Tundra to the Tahoe this is what I can tell you. Those toyotas are reliable as all get out. However, they have no technology in them what so ever. I'm not sure what the 2000 model Tahoe had back then that would be a must have, or if any.
Notorious Toyota issues are with the AIP. Around 100k the water pumps usually give out. As someone else mentioned, they did have rust issues. On the rusting frame issue, Toyota replaced all of the frames that qualified with brand new frames for free.
The thing that made me sell my Tundra was if you live in the country, toyota's have a known problem of mice getting into the cabin somehow. I don't know where they come in, but they do. My parents Camry had it. My wife's Camry has had them, and my Tundra had a TON of them. That was model year 09 Camry and 15 Camry, and a 16 Tundra. Can't imagine it wasn't an issue way back then.
Join a Seqouia forum (if there are any) and look at the issues. If there aren't any, join the TundraTalk community and read about the trucks that model year, because they're the same vehicles essentially.
I don't buy into the American made stuff. Tundra was the most American made truck the last few years, and GM had to be bailed out by the tax payers. Nothing says 'Merica like welfare I guess.
