This is what I and a few others here have done. Go to this website:
http://www.nissan-techinfo.com/nissan/
Create an account and go to view online subscription details. There is an option for a one day subscription (cost is $20).
Basically, select this option and you can 'view' the service manual for any Nissan you want, including your 2004 Titan. The loophole here is that you are also able to save each section of the manual to your computer. You need to save each section individually so be prepared to devote some time to it, but it's not that bad. The plus is you will have the complete service manual which you can save to CD, print out, do whatever with for $20 as opposed to $200 or more for a hardcopy. I usually just print out the section I'm interested in at the moment when I need it and that works well for me. This is probably your cheapest option IMO for a factory certified manual. Good Luck!
