Can any of you fun folks give any advice on this subject? Our MH is on a Ducato 230 with 2.8 id TD engine which is somewhat agricultural and unrefined. I like the sturdyness of it but the noise is so draining and tires me terribly even on 2-3 hour stints. A little Googling brought up www.noisekiller.co.uk and I wonder if anyone has recent experience of them. There is a thread or two on here (and a certain other 'factual' MH forum) but they are not so recent. My debate is whether to go for a pre-made kit like the one they seem to offer or to do it myself using whatever materials seem to make sense. Perhaps there's a knack to it with this type of Ducato which is handy to know? A hidden hole where noise comes in? A cheap yet effective material (carpet?) which does the job for a fraction of the cost?
