(StuartV): "...can it pull it when the battery is at minimum SOC at the start, with max load (14K #), and maintain the speed limit (up that whole grade they talk about)?"

What is your definition of "speed limit"? Per J2807, it can't fall below 40 MPH at any time, so per J2807, 40 MPH would be "speed limit". But if you are talking posted speed limit, depending on what the posted speed limit is, I'd guess that a Ramcharger starting with empty battery and pulling 14,000 lbs on ICE-generator alone probably won't be going 60 MPH.
