I tend to agree. Had the CRD been available I'd have that instead of the Hemi since the prime purpose for my WK2 is pulling a 5000 lb trailer (aside from normal around town work).
While the off the line performance of the Hemi seems to be lacking, mostly due to torque limiting and gearing IMHO, once you're moving it's quite responsive, much more so than the V6. When you double the vehicle's weight, like I do when towing my trailer, the motor really shines. With it set to tow/haul and the proper gear selected (3 or 4 depending on grade) you can maintain legal highway speed on any interstate grade without really breaking a sweat. I know because I did on my last trip running multiple 5% - 6% grades, the maximum standard for US highways, the WK2 Hemi performed flawlessly. In fact, I hooked up with a guy pulling a similar trailer behind an F-150 with the 4.6L modular motor and I walked away from him on every grade.
When I trade the Overland for an SRT8 in a few years it will all become a non-issue
