We just bought a 2006 Class C Winnebago and we love it except that the roof squeaks when you are going down the road. Sounds like rubber on rubber. Any suggestions for how to fix this problem.
Could be the cabover where it mounts to the van top. Ours was squeaking almost continuously and I took that area apart and found that most of the rivets had broken. Replaced them with machine screws with nylon nuts and the squeaking went away.
