Yep, that’s what I have... V6 4x4, SR5 (no rear locker)
Center diff (Torsen type) allows operation in:
2WD
4WD High Unlocked (aka AWD)
4WD High Locked (true 4x4)
4WD Low Unlocked (aka AWD)
4WD Low Locked (true 4x4)
My model year (2004) does not have an option to turn off traction control in 2WD or 4WD unlocked (aka AWD mode), which means you need to lock the center diff to disable VSC. If you want to have some fun in 2WD mode, you need to perform a slight modification (cut wire & add switch) to disable it.
I’ve had the truck in our family since new… but if I was to start this from fresh today, I would be looking for the V8 variant for no other reason than it’s a V8.
That said, 200k+ miles later, this thing is still solid. My favorite thing about the V6 motor is that is uses a timing chain which is good for the life of the engine, and the location of the oil filter. Easy of maintenance including things like spark plug changes are very easy.
