What speeds are you going to be going? What is your percentage time towing versus unloaded. I pull 10-12K with no issues (with my DP-Tuner), but I would imagine at 17K it would start to be a challenge. I wouldn't want to be going 70mph with 4.11 gears considering the mileage drop above 2000 RPM. If you are predominantly towing at 60-65 mph and below, I thing the 4.11s will serve you best. If you only tow periodically, then the 3.73 will do. Either way, you MUST get a transmission temperature gauge and a 6.0 transmission cooler or another JW transmission will be in your future shortly. The DP-Tunes make towing so much more enjoyable.

I wonder if clouds ever look down on us and say, "Hey, look - that one is shaped like an idiot!"
