I have the dolly and really like it. I have a 2016 Classic and my garage door leaves about 12 " on either size. The dolly permits me to 'thread the needle' with confidence. In addition, the unit is lightweight and therefore can be easily placed in my pick-up tow vehicle.
Incidentally, I also use a ProPride hitch on my AS. Sean @ ProPride fabricated a special adapter for me so that I could easily connect the ProPride hitch to the Parkit360 dolly. If you also use or plan to use a ProPride hitch (highly recommended for a 30' AS), I will send you pictures of the fabricated piece - just private message me.
Final thought: check your 2016 Classic bathroom mirror - mine just detached, fell to the floor after bouncing off the door, toilet, etc.
Good lick. See you on the trail. Dennis
