I used to have a 2004 Titan king cab and it just wasn't large enough when hauling people. I'm 6ft and if I had anybody taller than a toddler in the rear seats then I had to move my seat up and sat my balls on the steering wheel.
I now have a 2008 Titan Crew Cab and love it. Yes, I wish the bed was slightly larger, but it would be a pain to park! Nissan does make a 7ft bed option with the crew cab, and I believe Ford offers 6.5ft option with the crew cab, rather than the standard 5.5ft that comes with almost every crew cab.
I'm just about to pull the trigger on a new truck myself though. As much as I love my Titans, I can't seem to pick up a 2014 due to the styling being outdated. I test drove a 2014 Tundra crew max and loved it. It's like a limo, sits higher, wider, and the electronics are leaps and bounds ahead of the Titan as far as the stereo system and such. However, I will more than likely end up with a 2500 crew cab chevy z71 diesel LT/LTZ since I want a diesel.
Nonetheless, the crew cab is the way to go! You'll regret the extended cab!
