Yeah. I have 33's with 3.73. It runs fine but I'm also using the automatic and it does shift outta overdrive a lot when hills are involved. Also, it's pretty much a Daily Driver now. I did a lot more off-roading up at school, but haven't really had time (or money or a another vehicle if I break it) since I got my new job.
Also, if you want info on what gears your truck has, TRS has a great page that should help you out. I know it helped me out.
