Looking at that model on-line, it has an 'above the floor' slide but it's not a Schwintek with the drive tracks on the exterior. Is there a removable panel under the sink or oven? The drive will be inside the camper and above the floor.
Take off the panel beneath your stove. There is a spot in there to the right side..my hubby says you use the same 'wrench' that is used to raise/lower the stabilizing jacks...
