re: Any Trucks sold today offer a Manual Transmission?

They're more fuel efficient and easily integrated into the control scheme of the vehicle. Manuals introduce the option for the human (who may well be an idiot) to make decisions, which reduces overall efficiency and in turn increases emissions.

I've always had a manual vehicle. My truck has an automatic and I hate it when towing. It finds a way to make bad decisions. Upshift right as I'm getting to a hill. Upshift right when I'm getting ready to stop and need the braking. The vehicle can't predict what's about to happen, and the human can. That single factor is what makes people hate automatics and what doesn't get accounted for in the design.
