This is what the top will look like after I install more below with the batting. Going to go on the outer wall where fresh water line comes in and along fresh water tank and compartment wall as well. Then stuff as much as I can between back of camper and the back compartment wall under bed. Probably going to throw some batting under shower while I'm at it. The heat and noise mat will be in this weekend or early next week to seal everything up. The Styrofoam on the back wall will be flipped around and covered in material before being glued in place. I decided to leave the wall lights off since we never use them. I'm also going to remove the heater thermostat since we don't use the Gass heater. Have 2 electrics we use when in cold weather. Cuts down on having to buy gas since electric is included in camp fee.will update as work progresses.
