I have the same issue with my deluxe. Scamp
only uses the bottom center slide with what looks like a plastic C clip as a drawer glide, really no real drawer stop. You can do like they do in the std. trailer for drawer stops. They install long screws on the upper inside of the drawer sides to catch the inside if the cabinet face, or make some flip up drawer stops.
I'm sure the make a better bottom center drawer slide with a good drawer stop. I will look at them the next time I go to the hwd. store.
