I think I use what you are talking about. I got mine at Camping World. The link to the page is: https://www.campingworld.com/browse/...m?skuNum=29419
A reviewer says he thinks they aren't for heavy class A's. Mine is 21, 000 to 22,000 lbs., full of fuel, water, gear, and us. These orange pads have an X pattern on one side and are smooth on another. Depending on the ground, you use one side or the other (instructions are printed on the pads). They are very light and easy to clean and don't get water-logged, crack, splinter, or rot. I think they are great! They are $13.49 for 2, I paid $12.00 over a year ago. They are still a bargain to me.
