Anyway the wave of the future? .....carbon fiber.
Aluminum:
The funny thing is that GM spent the last couple years bashing Ford over the “weakness” of their new aluminum beds.
This year? GM’s new trucks all have aluminum beds. Whoops.
Dodge is projected to begin the move to aluminum for MY2019 when they start changing body panels from steel to aluminum.
CF isn’t a suitable material for truck beds because of what it does once its limits are exceeded. Once you get a crack, rip or tear in CF, the whole part just starts disintegrating/unraveling. Something the bike world is very familiar with, since no few bikes have had extensive carbon fiber parts in the last decade and a half.
