Don't know much about the C class rv's. But I can say, any squeak within the unit is wrong. Two surfaces rubbing together when they shouldn't is never ok. I'd have a dealer check it out before it gets worse. Preventative repairs can save ya $$$ down the road. Who knows, maybe just needs adjusting...like bgermane had done.
