Hello - We have a 2001 Ultra Supreme with flip jacks, and this is our 1st RV. They flip down then extend. I have heard about getting Snap Pads but they do not make them for our jacks. Not even sure what exactly they do. Our jacks are 5" x 4". Are there any suggestions on what we could use to widen the footprint when we lower the jacks to make them more stable. Anything out there permanent or easy to use each time? Do we even need anything?
