Have a Volvo 780 455 horsepower 12-spd auto can I do heavy haul

I just purchased a RGN 40 ton trailer and I want to know if I can do any heavy hauling with my Volvo 780 455 horsepower 12 speed auto transmission

 

2016

 

I'm not trying to pull crazy I was just trying to get my feet wet and try to stay with loads 55-60k that will keep my overall weight under 100,000
My truck weight is 20300lbs my trailer weight is 15300lbs I run out west here in America I avoid the big mountains on 70 in Colorado I try to avoid all of the big mountains I run a lot of flat land from Chicago all the way to Boise Idaho on 80 so you say your trucks in Canada like the one I have run heavy with no problem

 

Not looking to go that heavy just trying to stay right around that $100,000 and under just want to get where I'm making a little bit more money where I can step up and get me a more powerful truck thank you for answering my question

 

Ok so 500 with that 12-speed eye shift transmission will be okay for how much weight can I pull with no problem if you can tell me

 

Cool
