I'm the one that modified the sofa front on my '08 210WBS so that it "snaps" on and off
If you pry those two cloth covered buttons off, you'll find two screws under them. The covers just pop off and back on. Remove the screws and the front will then be hanging from the gaucho sofa's front metal beam. If you raise the front of the sofa a couple of inches, the front panel can be lifted off the metal beam.
I braced and reinforced both ends of the box that the sofa sits on and installed furniture door clips down both sides along with a hinge across the top, instead of the hanger strips across the top. The front now pops open and swings up and the bracing and reinforcing on the ends keeps the sides "solid" so that flexing isn't an issue with the door clips becoming disconnected while going down the road. I put in "short" screws (I actually cut the original screws off so that they don't protrude through the front) and re-installed the covered buttons...just looking at it you'd never know the front opened.
