Yeah, when you take what amounts to an entire house and drive it down the road....Things are going to rattle and squeak. That only gets worse as they get older. Yes, there are things you can do to eliminate many of the rattles and squeaks, but its almost impossible to get rid of all such rattles and squeaks, permanently.
With a motorized RV (Motorhome), you are going to hear all those, while you don't with a towable RV (trailer). Its just one of the things you have to live with, in return for all the other conveniences/luxuries that a motorized unit provides that you don't get in a towable.
That said, this is also one of those deals where 'you get what you pay for'. With a $60,000 entry level Class C, yeah, you're going to get a lot of rattles. Especially as they get old. Step up to a quality super C unit, there will be less rattles. Step up to a Class A (and really open up the checkbook, haha), and you will have a MUUUCH quieter ride.
