I would love to have low body trailers along with more dollys fit for heavy hauling. I'm sure I'm not the only one who tried putting five 30T steel coils in one of the current trailers only for them to totally break apart (understadably). Jokes aside, these could make very interresting configurations, and would allow for the weight of any cargo you transport to be redistributed evenly throughout the wheels, just like in real life. So you could haul things that would normally (literally) burst your tires.
