Ok, so no responses but tackled it today:
All in all - just a couple hours to get the couch out - taking time to individually package all the parts / label / take the pics / etc. in case we put it back at some point.
This worked easiest when the sofa was 1/2 way between couch and bed so you can see all the hardware.
The Seat is bolted to the couch frame with four bolts - they are welded so just need to remove the nuts and the washers. These are 1/2 inch - deep socket worked great.
Once those four are removed you can take the seat section off and out of the camper.
The back of the couch comes off the same way - four nuts / washers all same 1/2 inch socket size.
Once that is removed you have the frame and arm sections left.
So now we need to remove the arms / end sections from the frame.
Will need Phillips screwdriver for these. There are five of them that go through the frame into the arm / end section. White plastic spacers between the frame and the end section also. Can see a couple of the screws and the spacer in this pic.
Once those are gone we are just left with the frame and the section held to the sub floor.
To remove the main section of the frame from the portion tied to floor will need 1/2 inch socket and 1/2 inch box wrench since these are bolt and nut both - not welded bolt like those above.
You can see the two bolts in the above pic with the washers going down into the bottom portion.
Once these are removed we just have the portion connected to the subfloor. These are 9/16 and are coarse wood screws to get down into the subfloor.
The subwoofer is also under the couch - there are long screws on each end and one holding the wiring harness in place - we removed this as well since it will be relocated.
Jack Knife gone and cleaning up carpet
Ok, now for the reason we took it out in the first place:
Much more comfortable - came with individual foot rests as well. Rocker / swivel / recline. Searched all around Columbus Ohio since we wanted to make sure they were comfortable before we bought. Ended up finding at Big Lots of all places.
Now if we are watching the TV that is in the cab over portion we can swivel and be comfortable!
Hope this helps someone else...
