Weight allowance

Hi all, First things first, I created this account for my dad who is a career specialized heavy hauler but I will be using it also. I am 20 and have my intrastate class a, Im starting run local in ky with a 2004 dodge 3500 and 40 foot gooseneck also I own a 1986 kw w9 that is a look alike to my dads 85 model kw. Both have been stretched by kw of Evansville to 308" wheelbase tanks moved to weight distribute and tag axles added and floater front rubber.

My question is for my dually, My truck has a gvwr of 11000lb, trailer gvwr is 30,000lb and trailer weighs apprx 6700lbs. How much weight can I haul with the setup?

 

OK maybe I should've included that, my trailer has 3 10k axles with duals each tire has a load rating of 3090 lbs per tire which adds up to 37,080 lbs. the trucks tires are rated at 3250 per tire adding up to 19,500lbs.

 

Not planning on a 56000lb haul with the dually, it usually pulls bobcats, backhoes, small trackhoes and upto a small d4 dozer, equipment of that sort. I was just curious as this was a discussion brought up at a friends farm.

 

Have a feeling im fixing to look stupid but no I don't.

 

Thinking I should never have asked this question on here period,
