Thanks for the information. My experience towing my 23ft, 5000lb trailer from Minnesota to Colorado and back was good (around a 1000 miles each way). I found a legitimate role for the paddle shifters when ascending or descending the mountains or long up or down grades. Pulling a trailer with a Jeep is a little more intense than just driving. The stopping distances and some of the wind issues play a definite factor. What I noticed most is the suction I feel just prior to being passed by a semi. It sucks you around a bit but not too bad. My milage tended to be in the 13 to 14 range driving between 55 and 65 mph. This past weekend I drove without my trailer from Minnesota to Ann Arbor, Michigan - a 600+ mile trip and got 30 mpg which made me happy. I found the accelerating with a trailer easy with the diesel. It has lots of guts. It tends to be a little less responsive if you step it down at 60mph while trailering. When going 60mph I felt it worked better in 7th gear rather than 8th. Using the paddle shifters helped maintain the lower gear.
