We basically copied the Lange hoist and it probably cost us $125 at most. I have left it up there for over a month at a time and inspected and everything looks great. I am quite confident that hanging it for a season would be no problem. We just attached an eye hook to the storage area in our garage and cliped it to the window and the hoist hook with carabineers
to keep it from spinning.
And building it was a good bonding experience with my Jeep!
I can guarantee that the top loves me for it because otherwise I am sure I would have dinged it up a few times lifting it on and off.
I would post a picture but it says the file it too large. I have no idea how to re-size it....
