All I can say is...I LOVE MY NEW CHEVY!!! What an amazing tow vehicle...bar none!!! I thought the Kodiak C4500 was a towing beast...well, it didn't have anything on this new 3500HD!! It has a higher GCWR, higher TT and 5er tow rating...and does it while riding like a Cadilac!
Now, "why did I buy a Chevy, you ask"? Before the Kodiak we had a '98 Dodge..absolutely loved that Cummins, but never really trusted the tranny, and until June of this year (won't hit the dealers till then) Dodge didn't make anything that could handle our load...and still don't trust the tranny.
We really loved the Duramax and Allison combination in the Kodiak, it served us flawlessly, but it's still a work truck no matter how much you dress it up...and it rode like one. Probably would have never bought it if any of the Big 3 had made a truck capable of our load back in '07.
As for Ford...well never had a Ford, that in our opinion was ever worth a plug nickle, and after watching their last two diesel "debacles"...not a chance!!
This left us with the Chevy, which has been completely revamped...right down to the great new fully boxed frame! We've got almost 2,000 miles on it already...700 of that towing, and we COULD NOT BE HAPPIER!! JMHO!!
