I'm fighting rust too in my 3rd gen. I'm in SC, but the truck was previously a 1 owner vehicle in NJ.
The rust is much much better than I thought it would be, but there is one pocket that put a hole in my body, just behind where the runningboards used to be.
An angle grinder and rust...

My 2002 SR5. Bought it at 120K miles and was a 1 owner, garage kept truck. Added some goodies like a Toytec lift and the Tundra big brake upgrade, plus some other maintenance items.
