Thought I'd share my experience for those like me who rarely tow with their Armadas. Just got back from 1400 mile trip towing 6 x 12 foot enclosed trailer through Ohio, Kentucky, and Tennessee with the Armada, which now has 9000 miles on it. Dry weight of trailer was 1800 pounds and truck was fully loaded as well. Had around 1500-2000 additional pounds loaded in the trailer for first half of trip and averaged 12.8 mpg. I thought this was pretty good given hills and speed (70mph in most places, even faster in others). On the way back we had less than 1000 pounds in trailer and averaged 13.8 mpg. Also not too bad and better than I expected. I used the tow mode and the Armada rarely had to downshift, even over relatively steep grades. Also, the transmission temp stayed cool per the gauge.
Overall, the Armada did quite well and had no problems with acceleration/sway/stopping. I realize this was a light load that these trucks should handle with ease and I was glad when that was the case. I recall pulling a similar trailer/load a few years ago with our Grand Cherokee (4.7HO v8) and it was not as pleasant experience an experience. The Jeep had enough power but it felt like the tail was wagging the dog. Not a very reassuring feeling with your family in the car with you!
