I don't have a generator compartment.
Nor a rear bumper.
But I could add another cargo carrier to the rear hitch. I've done that before but it really makes getting in and out of the rear door an issue.
I guess the concern has to be someone running into you from the rear or me running into someone else in front.
Given those two choices, I think I would rather put my trust into my own driving rather than trusting the driving of someone else behind me.
I can't be one of the few people that ever thought about this.
