The trailer hitch is mounted at the heel, rated for standard tongue weight, and accepts any compatible tow attachment the operator deems necessary for the journey ahead. The hitch does not face forward. The hitch has never faced forward. This is not an oversight. What gets attached to the back is the operator's business. What gets left behind is everyone else's. Back Door is available in one orientation because the other orientation is just a different shoe and that shoe does not have a hitch.",
