I finally found what I have now and need to replace!
Go to Ranger Design - Garmin GPS - Landing Strips - Cheeper Creeper - Oil Change Wonder
if you would like to see the product. They are called Landing Strips. Since I purchased the product in 05 they have made changes to the plastic formula and added additional chemicals to make the product last longer in a sunny environment.
It's interesting how the mind works. I came across some literature for their Oil Change Wonder which I had also purchase in 05. When I saw this, the "light bulb" clicked on. Went to the web site and there were the Landing Strips.
Another RV adventure completed and I didn't even leave the stick house.
