Itasca Horizon Electrical problems by year

Our motorhome had a hamsar electro-magnetic flasher which is used to make the hazard lights and left/right signal blink. It is located in the fuse box in the outside compartment, near driver's side. It started smoking and smelled burned, lots of smoke started coming into the motorhome. The hazard were not in use at the time - we were just parked and it was off. We removed the device and it was entirely melted. Not sure what caused this, but if we were not in the vehicle at the time it started burning/melting, it would have caused a fire. I have a picture of this if needed. *Tr

Coach was filled with an acrid smoke. It was found that hydraulic lines melted, allowing slide outs to move during travel melted hydraulic lines needed to be replaced, and installed heat shields-by frieghtliner. Consumer was told that the problem wasn't chassis, but it was due to the coach. Cause of the problem still exists. *Scc....*Ak
