Here are the details:
2004
4dr sr5 sport v8 auto 4w
I have 3 kids in car seats and 1 in a booster, would this car work for me?

I believe it only seats 5

I have a 2005, so it is the same as what U describe.

Does it have 3rd row seating?

I do not have 3rd row, so I am not sure what would fit back there

Mine can handle two boosters in the middle row, not three. I think that is too tight for three. Two is the max.

If it has third row seating you may fit 2 back there.
