YEP, that would work, Just make sure you get the 3.73 rear end.
Now as far as sway control goes they are suppose to have it built in, and I remember seeing a video on it.
Personally, it looks like a fancy anti slip deal. I would still put a real anti sway bar on it. They aren't that expensive and they really work well....
Just make sure you get the right tow package they make a lot of different ones... and you want the double cab with the 145 in wheel base not the short 126 in one..
May you have at least one sunny day, and a soft chair to sit in..
