I've heard specs for the new Super Duty F*rds.

Their older chassis used to be 0.255" thick on the models starting in the late 90's. The 2004 model has a chassis 0.285"! (about double the thickness on the 88-98 GM ton)

BTW anything as thick or thicker than 0.250" is considered "plate metal" not sheet metal.

If you're interested you could probably check the frame thickness just by looking under the truck with a flashlight and machinist's ruler (something that measures 1/100's of an inch) a micrometer or vernier calipers; as long as the chassis is still an "open-C channel" shape in the back. That's what I saw on the 1/2 ton GMC, open C channel.
