I pull a 20 ton excavator with a pintal hitch, three axle trailer that dry weighs about 10K with a 4 axle Mack dump truck, that Mack dry weighs about 24K. So this roughly follows Marty's rule of thumb, but the idea that the power unit cant weigh less than what is being towed is ridiculous.
Your trailer is overweight if you do that, that’s 50,000 pounds on three trailer axles, unless you have a heck of an axle spread.
I’m a heavy-truck guy too, mostly cranes, also dumps and flatbeds.
I’m not saying you can’t pull a trailer that’s heavier than the truck, just that it gets sketchy on a bumper hitch. You can’t say the lighter truck/heavier trailer combo drives better that the heavier truck/lighter trailer.
You never drive a dump truck with the truck box empty and the trailer full.
