The entire sofabed does come out rather simply by unscrewing the four bolts UNDER the metal frame of the seat. It will take two people though to comfortably lift it onto the overcab bed out (of the way) while you work underneath.? While you are under there you can do a complete vacuuming and cleaning of the area that will likely have gotten dirty by this time.? Don't be surprised if you find loose change!!
Also while you are at it, Winnebagos are known for the screws working loose that keep the exterior outside storage box attached to the side walls.? Tighten all the screws surrounding it, and also seal any cracks you find everywhere, like possibly some towards the other end of the sofa, to deter any mice coming in.
Now for the most important tip!? When you put the sofabed back, move it a few more inches towards the outside wall to get a noticeably wider center aisle.? (You will need to drill 4 new holes in the wood support frame.)? If the sofabed won't go all the way back because the side valances for the windows are too low, you can unscrew those and move them up a bit as well, so that the sofa's back fits under them.

This modification to make the aisle wider is one that a lot of Toyota Winnebago owners have done, and it is a great improvement for more room to move around in the coach.
