Hi, my name is rphoto2001 and I own a 2000 win Journey. Would like to know if anyone knows where to get the insulation for the water heater unit. The existing insulation got damaged once the coolant line disconnected and drenched it with fluid. Tried to insulate it with regular insulation but am afraid it will not withstand the heat and create a fire hazard. A new 10 gal unit is a bit expensive and my unit is still functional. Just needs the outer box cover with insulation. Any help will be highly appreciated.
