Did someone say
Electric Truck? LOL!
Actually I was going to post anyway as I just returned from the NAIAS (The Detroit Auto show) and saw the GMC tailgate (and they had the CarbonPro box "exposed" on display too).
The Denali they were showing with the tailgate had a stereo in it--sounded pretty good too.
I'd buy a truck with that tailgate if I were buying (I had one of the first tailgate steps in my F-350 and loved it).
