I have a 2015 36ft HR with a gas v10. When I drive up a hill (doesn’t have to be much) the fan on the dash quits & goes to the defrost. It doesn’t matter if it is outside are, AC, or heat. The Ford truck & RV center had it for 3 weeks & said it was an actuator. They said it was an RV problem. Then the RV repair (where I bought it) center replaced the actuator with no results. After 4 weeks in & out of there shop they gave up saying it is a Ford problem. The Ford truck center does not want to see me again. I now it is a vacuum problem but where? Where is the vacuum reservoir on a class A gas rig?
