I went to that Website.
It has a Pic of the Chevy and Dodge on some kind of Ramp to test the RTI of the Trucks, I noticed that the Chevy has No rear swaybar, Thus causing the rear the Droop a Little More.
I can tell you that I Have stuffed my 33" tires all the way in the wheel wells With the Front swaybar disconnected,
I didnt order the truck with the camper pkg, So I dont have a rear swaybar.
I have dents in my rear shock tubes from the frame hitting the shocks under extreme flex.
Thats piston from the DuraLube looks like it has a real small skirt too!
