I have the Harbor, the first time I used it I sratched my rims, also scratched them doing it the bucket way. I will let you know next time I try it maybe next week, because now I drilled 2 3/8 holes into my garage concreat and installed threaded anchors. Then I bought 1 12in threaded rod (3/8 of course) and hacksawed the desired length that will screw into the anchor and above the base of the Changer and screw washer and nut on top of that. Now the thing is rock SOLID. As far as garage space, I just unscrew the Rods and remove the changer and back in the shed she goes:thumbsup:
