Mine is the wrong GMC, and year. But ducts are ducts. RIGHT. I lacked volume and heat from a duct to the rear in our 26'. Mice, and ducts joints that had pulled apart over the years was my problem. So I replaced the ducts with alum solid as much as possible. Then screwed, and taped all joints. Next used that silver bubble wrap insulation, and tape to cover all ducts. Now I have temps at a heat vent discharge near the furnace in the front at 151 degrees. At the very rear the readings are 147 degrees. I have a total of 4 heat discharge vents. So now we have quick, and even heat front to back. Plus furnace cycles are much shorter. And the food in the cabinets isn't precooked. Bob Dunahugh 78 Royale. Iowa
