I towed around 11K which is the heaviest load ever for my Cummins. Each of the 3 pallets of deck stone were around 3000LBS. One in the truck and two on a flatbed trailer. The truck had plenty of get up and go to tow atleast 2 more pallets easily!! I did have a horrible vibration in first and second, kinda like spring twisting or axel twisting. I remember reading about it somewhere. Once I got up to 30MPH or so I could lay into the throttle and make the ol' Cummins do it's magic. My friend that was with me had never been in a Cummins powered truck before, well to say the least he is a believer now! I got 14MPG towing that load for 200+ miles.
Does anyone know about that vibration / hop in lower gears loaded?
