I would think that it would also depend upon what mode the truck is operating in. Towing mode should logically reserve any battery availability for getting a load moving (torque) and possibly up those hills at near maximum capacity to provide a little more oomph. In EcoMode you'd expect the computer to sense the driving conditions and provide battery accordingly. I guess if there was a normal mode it would be set parameters, something like under 20 mph and or when using high horsepower. I have to say, I'm disappointed but happy why it couldn't be possible to have a similar sized battery with a plug in port I don't know. If the battery is supposed to aid the engine in any way, (which it is obviously), than what happens when I'm ready to start a trip with a heavy load? Wouldn't it be nice to not have to go drive around for that little bit of battery power? Plugging the truck in for 30 minutes to go from dead to full once in a while could prove beneficial. I'm suggesting the same battery and weight plus plug in, that would have been huge!
