OK, did some research on my truck for those of you who've brought up towing concerns. It looks like I have about 3,100# of cargo, my rear tires have over 3,100# and my rear axle has a 6,200 # rating.

Now, I'm a little confused, what do I do to "do the math". The trailer's pin rating is roughly 2,000. Of course, that's dry. How do you determine how much weight is on the pin once loaded down.


So what is the "formula" for towing a 5er? """

Please tell us exactly what Duramax You have.

My Duramax in my signature has a gvw of 9200 and going thru the scales with a full fuel tank, my 135 pound wife, 20 pound dog , 80 pound trailer hitch ,40 pound tool kit in the box , my weight is 7380 pounds. My duramax is 2wd so lighter than a 4w4.

So my cargo carrying limit is about 1800. When I throw a few things in the box like golf clubs, bbq , chairs,etc. and hook the trailer on I am near maximum gvw for the truck.

I don't know how You get 3100 cargo ability on your Duramax. Is it a Dually? More details needed!!!

Ideal method would to scale the unit but pin weight is approx. 20 to 25% of the trailer weight. i.e. 13,000 GVWR fifth wheel will have 2600 - 3250 pounds of pin weight.

OP's original post says he has a 2013 2500HD Duaramax. Like your 2007 my old 2010 2500HD had the same GVWR of 9200. 2013's have a higher GVWR of 10,000 pounds. RAWR is still the same @ 6200 which would be the weight ratings of E rated tires.

Personally... we got rid of the 2500HD to a dually because 2000 pounds was not enough capacity for our trailer with almost 3000 pounds of pin weight plus the weight of the hitch etc...
