Removed it from my Class A
Remove all the bolts holding down the frame, using a lever raise the frame starting at one end and support the frame using 2x4 blocks, one in back and one in front. Repeat for middle and other end.
Make longer 2x4 blocks the length of each frame, front to back. Lever the frame up so that it is supported on two high 2x4.
The frame is now up and above the bolts coming out of the floor so the sofa can slide out without lifting.
Slide out so it can be lifted and lift so it stands on one end. Then out the door on end.
