Battle of the heavy weights

Assuming its a legit test, its impressive. Especially since the 2011 Duramax smoked both of these trucks on similar tests a couple years ago. Those well publicized tests run by different organizations all came up with the same result as the winner. If this test is confirmed by others, I think it speaks volumes of how far the performance in these HD trucks has come in just a couple years (at least Ram and Ford). I don't think the 2015 GM HD will fair any better since the running gear is the same for now as I understand. I will still buy the GM product regardless because I am hard headed like that, but the 30K trailer capacity of the Ram does pull on me.
