The front cabinets on my 2013 Winnebago Vista 30t always seem so hot. I don't have any electronic components in them either. So I decided to insulate them using a roll of 6 inch thick non backed attic insulation. I started off by removing all the carpeted panels. Then I measured out each cabinet and begun cutting and fitting the insulation (I also placed insulation under any cables to help prevent them from rattling around in the cabinet). After placing the insulation in all the open spaces I reinstalled the carpeted panels and cleaned up all the excess insulation (vacuumed and wiped down all surfaces). It didn't take long and you could feel the difference in temperature in the cabinets, much cooler.

That’s great! When I was at the factory for service I asked them to fix the high heat in the overhead cabinet. I was not surprised that they would not but was surprised that they said “the heat up there is a design flaw not a warranty repair.” They said they are totally aware of the issue. They suggested that I do as you have done.

Nice solution, nice craftsmanship. Six inch insulation. Impressive!
Shared your heat distress, but use our cabinets for entertainment components. Still, managed to face some 2inch foam with matching fabric and glue to roof. Added a pancake fan to circulate the air.
Every little bit helps!
Fair Winds and Following Seas!

Been waiting to do just that, but I may use encapsulated insulation. I'm not sure if the dust would migrate down on a rough road but I've very sensative to that stuff.
