Much much research went into the purchase of the truck, with the notion of what 5th wheel we wanted to purchase.
We love love our 2017 Deisel Duramax 2500HD Long bed crew cab. All of the research we did on the manufacturers websites showed us 18,100 towing capacity. With a Gross COMBINED weight of 25,000 and some change.
After the purchase of the truck and the 5th wheel, we read the manual (plus the duramax addon manual) from cover to cover.
To our surprise, the GCWR is listed at the 25,000 but the trailer rating is only 12K?
This is totally baffling us? We calculated the dry weight of the truck, added a full tank of gas, the weight of the fifth wheel hitch, people weight, and a couple hundred extra pounds of 'stuff' and we came up with 7,735 lbs. The GVWR of the truck in and of itself is 9900.
So even fully loaded with rocks or something crazy at 9900, there should be a towing capacity of 15,000 plus.
Where is my math wrong here? How can the Gross Combined weight be so large, but you cant pull the difference (legally).
Truck GVWR = 9900
Truck Towing GCWR = 25000
5th wheel GVWR = 17000
