We have a 2006 Dodge 2500 Truck we pull a 30 ft fifth wheel...we go over 60about 65 and there is a roaring noise that seems to be coming from the rear end of truck. Any ideas what this might be...
My 2012 GMC started doing this and it turned out it was the tread separating on the rear tires. The wonderful Good(for a)Year OEM tires that came on it with 30K miles. Not saying that is your problem but worth looking into. Also made my stabilitrak error light come on to.
