Creaks, Squeaks, and Rattles

Having caravanned for 20 years, it may well be that our vans creaked and rattled when on the move, but of course not travelling in them, we never heard it.

Now with our first motorhome, albeit only a couple years old, and low mileage, we have been astonished at how noisy it is when travelling.

Not what we have put in it, but the furniture, microwave, Remis blinds etc, etc

I have been going around putting sticky backed plastic pads on door, and draw shuts, tightening screws, and wedging bits of foam rubber into joints that I think are squeaking, etc, but it seems to be an impossible task.

Are all motorhomes inherently noisy, and if so do you drive with ear plugs in? 

Its a real pleasure to get into the silence of the car.
