What did you do to your Class C MH today???

I removed the spare tire from the neat rack, between the frame rails on my 31C, which I am selling. That was lots of fun, I realized after the fact that the rack possibly hasn't been touched in about 12 years. The outside rear tire has a bad slice/gouge in it, so I thought I would put the spare in its place. Of course just to make things more interesting the tire with the slice is on an aluminum rim, while the spare naturally is on a steel rim. I got the spare out and it still had the label on the tread, so its obviously never been used. Of course after checking the tire, I found that it was made in 2003. So I have a never been used 12 year old tire. :S
