My wife wanted a pantry in the Legacy. So she pointed to the dinette and said "You could build a slide drawer in there couldn't you. YES DEAR. So here it is. Not AS hard as I thought but hard enough.
First off.... There are three and only three screws holding the bench to the slide. Remove them and pull the bench out.
Cut the seams in the end of the bench across the top end and down the middle panel seams. Pull staples and Fold the material back to expose the end of the bench. Pull off the cardboard face that exposes the 1x1s that form the arched end.
Pull the 30 or so staples out of the particle board that secure it to the frame. This is a huge pain in the arse but you will find a method. We used a punch to start a hole under the staple then pulled them out with a pointed hook and pliers.
Now you should be able to just lift the arched end off. On the side that faced the drivers seat we glued and screwed a 1x2 so that there would be an edge sticking out that side that you can use to open the drawer with.
Go talk someone into covering that arched end to match the seams in the other bench. This is where I tell you it took my wife over a month of run-a-rounds to finally get a very nice lady in the FR parts department to locate and order us matching fabric.
I ordered 500 lb capacity 30 inch side slides to put on the drawer They are very expensive and lighter weight slide may work just as well.
I built a box 38 inches long and as wide as I needed to to fit flush with the slides. I added 1x2s right on top of the bottom frame 1x2s to give the slides a place to mount.
Next we attached the slides to the bench and the box and slid it into place. Finally we mounted the face/arch of the drawer to the box
Seems to be perfect and my wife thinks I'm DA MAN.
