I'm trying to think of a way to raise a 12x8 foot porch up 15 feet. Let
me explain: The trailer house was moved to a new location. The porch
came with the trailer house. The porch was free standing, only
connected to the trailer by a few screws and some flashing to join the
roofs. (This is a porch with walls and a roof, which has six 4x4 legs).

I only read the description once, and I'm not sure I'm picturing it,
but

How about moving the trailer out of the way for a while, putting the
porch at the top of the hill, and lowering it into place? This might
be safer for the trailer too, out of the way so the porch can't fall
on it.
