We recently returned from camping in our 2010 Sport 22. I immediately noticed that the converter box, which in this model rests on the floor below the fridge, was loose. The left side of the box was away from the cabinet by about an inch, while the right side of the box is tight against the cabinet. I opened the drop down converter cover hoping to see a loose screw that just needed to be tightened, but there isn't anything obviously loose. Other than stuffing a wood shim between the converter and the floor
how do I go about reattaching the converter to the cabinet?
