Yes they needed to have the fifth wheel slid forward a couple notches where it as set might have had the perfect weight distribution to cross the scales but in long hard pulls where you are in the bottom gear there is enough torque on the larger engines to not only lift the left front steer tire but to permanently twist the frame.
sliding the fifth wheel a couple notches too far forward elevates a lot of the problem. once you find yourself in the bottom gear you don't let off until the top find the best torque RPM and stay there not more not less if you even let all the way up and gas on it again the driveline or a rear end the transmission or an axle is going to break every time. Always have the power divider locked in and if you have it the interaxle lock don't worry about gear bind there will be enough tire slippage to compensate for a short duration of a few miles.
Once a load such as this starts down hill even setting every brake on the rig is not going to stop it if the tires lock up. I've seen ruts cut into the asphalt from trying to stop going backwards.

Helping my brother get his shed kit home from Channel Lumber one Saturday morning we went up to get it & he decided he needed railroad ties for the base of the thing & we loaded up the shed kit & the the ties hanging way over the back of the dropped tailgate in my 1982 Toyota pick up & drove off. There was a railroad track that crossed the highway about 1/4 mile down & when I hit it in pretty tight traffic the front wheels bounced. I then found out at the first traffic light I could lift the front wheels off the pavement by hitting the gas not very hard. It was an scary, interesting & slow ride back to his place, 15 miles away.

Yep improper load balance and weight distribution has led to the woes of many drivers.
glad you made it home safe. Once the seat covers become a wedgie knuckles often turn white jaws get clenched and your heart rate goes through the roof and stays there until you get to where you are going.
