I know no one has talked about this for a while; but I have just viewed this.
I am trying to find out if the fifth wheel I have is too big for my 2500.
These numbers drive me crazy.
If you add the GAWR front (5,200#) and GAWR rear (6,010#) that is 11,210# but the GVRW is 9,000#. Why would these numbers be different?

Now the curb weight rear is 2,684# so subtract that from the GAWR rear (6,010#) and to me it sound like I could carry 3,326# on the rear axel. But you ad 3,326# to the base curb weight of the truck (7,032#) and you get 10,260# which is 1,260# over the GVWR. Why is that?

Ok so let’s say I am maxed out GCWR of 20,000# and GVRW is 9,000# so the fifth wheel would be 11,000#. So you do the required weight for the kingpin; 20% to 25% of the trailer that would be 2,200# to 2,750# at the kingpin. Well crap, I could not even do that with and empty truck and no driver because the total carry capacity for the truck is GVRW 9,000# minus the base curb weight of 7,032# and that’s only 1,968#!
After I load the family, the dog, some goodies, and the fuel lets say 968# that would leave me with being able to have a kingpin weight of 1,000# which would be a 4,000# fifth wheel.
Do they even come that small?

Here are some numbers I had from last weekend. Truck weight 7,850#. Truck weight with trailer attached 10,150#. So that gave me a kingpin weight of 2,300#. Trailer weight attached to truck 8,400#. So that would be a trailer weight of 10,700# and a combined truck trailer weight of 18,550#. The trailer has a GCWR of 12,120# so I was pretty empty.

What do you think?
Do you think I am safe with these weights even if I had more weight in the trailer?
If I keep the GCWR under 20,000# and the kingpin under 2,750# do you think that’s good?
Thanks for the help!
