Dumb question OP, but you say it has TRD stickers. Not sure if all TRDs in those years were all 4wd?
Is this 2wd or 4wd?
From my research, I believe someone added on the side TRD decals. They look old though so I am not too sure.
I read that the 6 lug models were either prerunner or trd but this one is def 2wd.
