GM just redesigned the frame on their HD truck for 2010 or 2011. The frame had been carryover from the old body style "GMT800" HDs made from 2001 to 2009 or 2010. IIRC it's fully boxed now, but was not before. Think it's the first fully boxed HD frame. That's what they're advertising here.F-150s, 2004+ are the most torsionally rigid feeling trucks I've ever driven. Ford has a similar comparison video for half tons: [ame=http://www.youtube.com/watch?v=huS-X0USuq0]YouTube - Strength of F-150 Backbone Gets Tested‏[/ame] Chevy does well, Dodge does okay, Toyota does incredible poorly (their frame looks like a bad copy of my 2004 Sierra).
