I am starting to look for a truck that will pull a 16,000# - 18,000# conventional boat trailer (not a load equalizing, 5th wheel or gooseneck) to replace my 2500HD.The Monroe Kodiak conversion looks very inviting with the exception of the engine/transmission. I am having a hard time understanding why GM is putting the 300HP/605# version of the Duramax in this series when they put the 360HP/650# version in the 2500/3500 series. Both engines make their power at almost exactly the same RPM. It would seem to me the additional 55# would pull a heavier load better, especially since both engines make their peak torque at 1600 RPM.
Do any of you 4500/5500 owners have any idea why GM puts the lower powered engine this series? Additionally, why use the 5 sp version of the Allison when the 6 sp is available. It seems to me the 350HP/650#, 6 sp version would be a lot better.
Any other options available to pull 16,000 - 18,000 without going to the International CTX?
Thanks
