I think if you plank the top of the three wheels, you can carry there another bobcat or medium size equipment legally and, the bucket can pass and rest in front of one bobcat I believe or, on top of the bobcat's bucket top or swinged/rotated up bobcat's bucket. Think about it or consult with your Lawyer or Highest Authorities if it's legal to do that.
DOT is really the only ones that would give them an issue, what matters is the weight distribution between the trailer and the drive axles and keeping height under 13’ 6”. But it also depends on the state.
