Well I towed with my 04 for the first time this weekend. I took a camping trip with my 30 ft. travel trailer and went about 180 miles round trip. I estimate the trailer weighs about 7500 lbs or so loaded. I also have an Equalizer Hitch and all stock suspension. I must say that I was very happy with the way the truck handled the trailer. It had plenty of power on the rolling hills I drove on and I love the big mirrors on the truck. I use to tow with a 2500 GMC HD gas motor and feel like my Titan pulled just as good if not better. Just for the record, I towed in 4th gear with tow/haul on as many of you have suggested. The trans temp. never even thought about getting hot.

Great news, I know these Titans are meant for towing and this obviously proves it!

I love the big tow mirrors and will be swapping my stock mirrors out soon.
