robot design question

[Otaku]

image is top view, and not to scale completely, but you get the general idea.

The question is "Is this legal?". In so far as what constitutes an "outside" edge. The rule's not completely unambiguious about this. Can parts of the robot "wrap around" the trailer so to speak? Would we be allowed to make a design that limits the lateral movement, through the placement of the hitch alone and no other modifications, of the trailer, assuming that trailer to robot contact is still going to be bumper-to-bumper?

EDIT: also, this design won't ever see field time, I kinda wanna keep the real one hidden, so just imagine that the trailer isn't as engulfed as it is here. The same questions apply, though.
