Sorry for the delay (fell off the earth) on this response...to your point, the 15 mpg part was unusual, but expected as I was basically going downhill. I had driven from Dillon, CO to Denver over the Eisenhower Tunnel in a similar fashion to the Ike Gauntlet. I filled up in Dillon and then averaged between 4.5 and 5 mpg up the 10 mile hill, and I kept the speed limit the entire way up. Then from Eisenhower down to Littleton, CO I did not re-adjust the average mpg and ended with 15+ on a total average once I got home. That included several more up and down hills between 60-70 mph and one more mountain pass before you head down into Denver (from Chief Hosa). My speed ranged from 55 to 80 depending upon where I was...and this truck handled it well.
I'd say more realistically though is I'm averaging 11 +/- mpg. And like a similar post spoke of this Titan is very solid when it tows, whether in the wind (side or headwind) or on hills up or down. If I was towing on the flat and on roads which had speeds in the 55-65 range I would expect this truck to pick up a couple more mpg, I just have too many hills around me.
My truck is now 14 months old and I've put 15k miles on it. This spring I installed the full K&N Air Intake kit.
I recently road-tripped 2000 miles back and forth to western Montana from Colorado (without a trailer) and even with some bad head winds and crosswinds, which the day before had blown over a few semis, this truck just drove right threw it and did not care. Having driven this trip too many times before in cars, trucks and midsize and full size SUVs, this was the easiest trip threw Wyoming I've ever had, and not because of the weather. With the wind and the constant speed of 80-82 mph, my mileage suffered obviously, but I still came home with high teen mileage and could best 20 mpg in some sections without the winds. On that total trip I believe my round trip mileage was 17 ish.
I'll be towing my 5k trailer at least 5 more times this summer. If things change I'll report in. Thanks...

My last one pulled 5-6k pounds easily and I figured this one should do the same if not better, and it does. I've towed my TT (24 foot, 5k) in the Colorado mountains twice since I bought it in May and both times this truck had no issues keeping up with the hills. I've hit 75-80 on the interstate and have not had any concerns on trailer sway, I may chime back in after I do a road trip north threw windy Wyoming. I would have preferred getting the trailer towing gears like my older truck had with the Big Tow package, but the new truck with the increased HP seems to make up for it fine in my book, and I am getting better mpg than my prior truck by about 1.5-2, it would get more if I didn't put my foot into it all of the time. With the newer 7 speed trans it does shift into what it feels to be a better gear for the towing situation you are in. So far towing over mountain passes only, and not really any flat stretches at all I have managed mpg averages of 11-15...not bad in my experience when I'm already starting out at 5200 ft elevation already. Hope this helps.
I sure am curious how you can get 11 to 15 mpg (US) towing a 5,000+ lb TT at 75 to 80 mph at a mile above sea level in mountainous terrian
