So, first I tried to sell it. No takers, even with a really low price. Then I tried giving it away. Everybody wanted it, but when they'd come look at it, knew it would be too hard to move. It does weigh over 800 pounds. Finally, the fourth person I asked said yes and we can do it with no problem.
They used a method called cribbing.
On moving day, my handyman and his assistant took out the big window. Then the family went to work. They built the crib up outside, moved the tub halfway thru the window, moved the blocks from the inside out and pushed the tub the rest of the way through. Then they lowered it on the trailer. Really, it was amazing and done so quickly! As they drove away, the handymen replaced the window. Now to clean the floor and move in my furniture. This is going to be my bedroom. Can't wait to watch the northern lights this winter.
