Roof Rack / Spare Tire Logistical Questions

[ROX]

I plan on having help get it up to the top, then using a rope (and a blanket) if I ever have to get it down. Once it's on the ground it becomes a road hazard cuz I can't lift it over my head. I was barely able to get it onto the spare tire carrier I had on my car for a week. I could probably get it in the back of the H2 if there wasn't always something back there. Just make sure it doesn't roll down into a ditch, or off a cliff or something when you let it down.
