SISSY STEP ?

Agreed. I think GM came out with some sort of composite bed to counter Ford's use of aluminum. They disparaged the aluminum bed because it might be damaged if you were an idiot and drop cinder blocks from eight feet overhead...
Lets see what happens to Ford trucks once the salt gets at them. Aluminum, salt, corrosion and spiked computer. Should be fun. Same as these self driving cars. Someone's brainstorm. What happens when the snow covers the sensors and rust starts eating the ground straps and causing spikes. Should be something like a Walmart parking lot. And we pay these idiots big bucks to design them DUH!!!!
