All the 08 and 09 Cruise units had a rear window. It does not open though.
Rear hitch is 2,500 gross, 200# tongue so that generally precludes putting a scooter on a rack back there. It's not a liability issue as someone else posted, but rather, due to the front end getting *very* light with that much weight hanging off the rear. Don't forget, the water tank and the cargo compartment are both back there as well.
Put the scooter on a rack mounted up front and you'll be good to go, but you will chew up ball joints faster with the additional weight in the front.
