Background Info:
A friend of mine has similar truck except 13,200lbs front, 40K lbs rears, 13 speed transmission and 2.64 gears at 257” wheelbase.

His empty weight for the same trailer is:
12,960 on steers / 17,640 on drives, 16,160 on tandem(third axle up) / Grossing at 46,760lbs

The trailer is an 3 axle extendable step deck, 43’ to 67’ plus 5’ “weight bearing” bumper. Upper deck is 10’.

The loads are generators and other box shaped freight, weighing anywhere between 25K lbs (usually short) or 70K lbs (usually long). Rarely will pick up ann outhouse that is short <40’ but heavy 65-75K lbs. I would say average weights would be 46K.

98% of the time, we drive loaded for 650+ miles then drive back empty. 2% of the time we will find whatever non-divisible overweight load we can or a 34K divisible load back home.


Did I screw up and went too much? What’s your opinion?

My friend has thinner rails, and less securement than I will. Which will add roughly 1K lbs extra on top of my configuration.

I do plan on purchasing an extendable RGN with flips and a 2 axle jo-dog to pull heavier equipment in the future. That’s ~3 years from now.

 

Username does indicate why lol.
