What Are These Things?

[Jim_PEI]

I bought my Class A 2008 Independence about a year and a half ago, in storage for about 12 months, and have about 6-8 of these "things" and I don't know what they are. I found them in one of my storage bays. They are about two feet long, made of metal (heavy), circluar of about two inches in diameter, and with a square 3-4 inch pad at one end. They are pretty heavy for not being very big, so probably are important. I thought maybe for the awning, but don't have a clue.

Thanks, Jim
