As the title states. I've been trying to find a forum dealing with heavy duty trucks like Peterbilt, Freightliner, etc. Does anyone know of any? I've only found one at trucknet but there's more drivers than mechanics. I'm looking for one like this site where you can get ideas and help from knowledgeable people and don't have to wait three months for an answer. There has to be a place where heavy duty techs gather.
