So we are now waiting on the contractor to make a hole in his house for a winch cable.
Another solution has come up... The carpenter that was doing the cutting of the siding/drywall has access to a tilt bed truck with a 6000 crane on it, and a stinger head (a head that rotates +-90 degrees). With that, we can obviate the need for rollers, and hoist everything onto the flatbed. Might make it a lot easier!
He and I will have a look on Tuesday to see if it will work!
Rest your back.ANyway, taking the weekend off, and then restarting next week! 75% done and no roadblocks yet!
