Im a 5th wheel camper that tows with a 05 Dodge3500PU with a Cummins..Being a former Dodge Mechanic, allows me to fix most things on the truck or camper....We, my wife and I talk about switching to a class A, most likely a used 40-42' DP...Then I read post like this that has happened to you and a cost of 1,800$ for a problem of no power..1,800$ to me is some nice upgrades that I could do to the PU or the 5er...I know it happens rarely but the though of it is in my head and we travel out west to the Rockies ever other year, so we like to travel with our RV. The best of luck with your A class and enjoy the summer
