I have the 07 new model lmm crew short 2500 4x4. The best advice I can give when towing is keep your speed down. I did a trip, with a 28' 5th 9500, and the majority of the time it was flat freeway. If I ran the speed limit of 120k it sucked it up but I tried keeping it at 85 to 90, and enjoyed the drive and scenery, the difference was huge. I had the edge tuner and the fuel use was displayed, well the numbers were very different. Slow down and enjoy !
