Put the transmission in second, keep your accelerator foot on the seat next to you and let out on the clutch. Phord will die. I don't think the Chevvy will do any better except I haven't tried the Allison transmission yet. Try it on a Dodge and you will take off in 2nd, 3rd and 4th gears on a stock truck.
While towing my 33 ft fiver with GCWR at the max 20,000 pounds I can move the unit, uphill (6%grade), without pushing the throttle. What more can a diesel freak ask for?
