I hauled some cabinetry down from the manse up on top. Believe me, you don't need to worry about shoving it to the front of the bed!! I wouldn't try that thing anytime there was a combination of dew and freezing temps.
Only a nut would build something like that, but the story is the 'nut' caused grief for neighbors in back, and they refused to let him use their driveway access to the back of his property on top, which is a very gentle slope in comparison. Hence, the 'Hill from Hell'.
That concrete had to be very dry to not attempt to follow gravity when it was poured!
P.S. - Average frequency of snow, about once every ten years. Freezing temps at night for about one month per year. If coincidental with rain, maybe 5 or 6 times in that month.
