This may help, mine is a 2004 and has the Lippert slide mechanism and is the flush floor setup. Your slide drive I believe is a Barker unit if you have a couch/dinette slide. I did not notice your model number to look it up.
We have a jack knife sofa and table and chairs. What I am showing is the rub board that was screwed to the wall. The screws are buried in the carpet and hard to see, but they are in there. Feel around between the fibers and you will find the square head drive screws. If your does not have this strip, then they held it down another way.
On the slide sides, I had to use a sheet rock utility knife to cut the rub flush with the wall.
Here are the pics, hope this helps
Couch removed. The rug board is at the junction of the carpet at the wall. It holds the rug down to the slide floor/wall. Also have to take the couch supports at the wall out. Screws buried in that too.
All the screws used to hold that one 5.5 ft long strip
The rug board itself
Then carpet folds back once scored at wall
Pas exposed and then removed
Pad pulled back. Slide floor rot in the corner. That is another post on how to fix.
Hope this helps and good luck.
