Insulating front overhead in Class A

Every class A I have owned-all gas- have not had insulation behind the top front cabinets. In summer with sun it gets very hot in the cabinets and most had electrical devices such as satellite controller, switches and receivers. On one coach I placed regular blanket insulation in the area and it helped. The running lights and wires are in the area of course so foam does not seem to be a good idea. Any advice or experience?
