There is a valid argument wether or not the torsional rigidity is such a good thing. I have had a couple people complain about poor ride quality out of the 2011 trucks especially with a fairly pin heavy fifthwheel or gooseneck.
ride should comes from the suspension, not from the frame.

In an ideal world yes it should be the suspension doing the work of providing a nice ride.
The real issue is trying to anticipate how the ride will change as you take chassis flex out.
BINGO! we had 3 brand new trucks come back to the dealer ship last year with cracked frames! Snow plows are hard on trucks and GM did some much needed strengthening!There was a reason GM beefed the frame. Apparently they figured it wasn't strong enough.
That is the most asinine point of view i've seen in a long time. Undampened chassis flex to make it ride better? :roflmao:
I'm positive GM and Ford both employ an army of suspension engineers whos only job is to make sure things work properly in a tradeoff of ride quality vs load capacity and stability. "figuring it out" is what they do.
I have to fix the "solutions" on gm trucks every day.
Like I said in an ideal World a rock solid chassis and use the suspension to get a decent ride. But here in the real world there are financial limitations and unexpected results. Hence things like the 2011 hd that is very picky about ride height. I have already had to fix at lest 3 or 4 11's with ride related chassis issues.
I have no doubt the army of suspension engineers know many ways to address the issues caused by a rigid frame, but that would probably make the price of the truck too high to sell.
I have not yet been in one of the new HD Silverados or Sierras, but all the reviews I've read comparing GM, Dodge, and Ford rave about how well the GM trucks ride both loaded and unloaded.I have to fix the "solutions" on gm trucks every day.

So cranking the torsion bars make them ride like garbage? That's no big surprise. My dad's truck does the launch shudder thing, and his is an 07 LMM. Neither of those sound like chassis stiffness problems.Most have been pretty straight forward after I figured out the first one. If the z trim height is too high (cranked t bars) they get a pretty nasty slap down feeling.
The others are launch shudder problems which as of right now I don't have a warrantable fix for as of yet.
