08 340 TS .. main slide. (couch & dinnette)
Viewing the slide, looking at the couch, just behind the drivers seat ... floor and that wall came apart....busted loose all the way.
Tech. stated he spent 3-4 hours ... drilled for three large wood screws and refastened floor & wall. Covered with strip.
We paid out of pocket 420 bucks.
We had troubles with this slide since new. (( Even the ram, has been replaced)
Good luck.
