Product review (5 stars): Good for cabnits and single wide refrigerators.  Might not work for yoour double wide refrigerater like mine
Works as designed and is easy to adjust and install in your refrigerator.

Pros:
  1. Light weight
  2. Small enough for storage when not in use
  3. Very easy to adjust to different lengths
  4. Good for small refrigerators and small cabinets
  5. Good price

Cons:
  1. Not very useful for you double wide refrigerators maybe meant for single wide frigs.

Would I buy another YES and recommend this product for your RV.
