Greetings, we have a 2005 PW Dodge Plateau with an Onan generator. We have old (2007) information indicating that it is possible to quiet the generator using insulating blankets. Would like to put this to use but can't determine exactly what kind of "insulating blankets" would be appropriate (by thickness or brand or size of piece). Further details on how to attach the blanket around the generator would be helpful too. Any suggestions would be much appreciated. Thanks.
